Better Insights from Updated Charts and Graphs

Here at MxToolbox, we’re big fans of good graphs and charts that provide insights, show trends and give you decision-making information.  And, it always helps if they look good.

We’ve recently launched an update to all our charts and graphs for MxToolbox Professional users.  Now, paid users get graphs that are much more interactive with much more information. In short, this:


Becomes this:


Each data set can be selected, deselected and the timeline adjusted right from the graph.  And, we think the new graphics are beautiful, too…

We’ve added some color to our monitor tagging system

If you are currently monitoring a large volume of IP addresses or hostnames for your organization or on behalf of your clients, one of the most important requirements is the ability to quickly group and identify related monitors. For that reason, we added the ability to create tags a few years back as a way to easily identify groups of related monitors. For example: if you needed to monitor blacklists for multiple clients, you can easily create a tag for each individual client and assign that specific tag to the monitors related to that client.

As there is a growing need quickly identify groups of related monitors, MxToolbox recently added the ability to specify a color for your tags.  Now, you can make it easy to visually identify groups of related monitors. After creating a tag you can assign it one of eight color types by selecting the color palette square next to your existing tags.

To start adding color to your tags simply login to your account and visit the Tag Manager by selecting Tags from the black navigation menu.

Tags are available to all monitoring accounts starting at our MxWatch Basic Plan and above.  We hope that tags, and now colored tags, will make it easier for you to do your day-to-day tasks with MxToolbox.

Availability Report: Uptime % and Downtime for all your monitors

These days website or app uptime is a crucial aspect to any business online. If your website goes down for any reason your customers and business suffers. MxToolbox Monitoring offers two ways to report on the uptime of your servers:

  • Uptime Reports
  • Availability Reports

Uptime Reporting for Web, DNS, and other critical services give you Summary Uptime and Downtime reporting to protect on each monitor.  Simply select the monitor to see how we protect your business and customer satisfaction.   Uptime monitoring tracks performance over time in order to compare how your server is performing today vs last month or last week.

Our Availability Report allows you to view the Uptime %, Downtime, and displays the current status for all your monitors. The Availability Report allows you to specify the date range so you can recall historical Uptime/Downtime statistics and issues.  This is particularly valuable when you want to show upper management how well things have been running over the past quarter or year or justify additional expenditures for servers.  In addition, you can access specific monitors directly from the Availability Report to checkout current status and specific issues.

With our new Availability and Uptime Reporting, MxToolbox Monitoring gives you even more insight into how your servers, and business, are running.

HTTP/S Screenshots: Lookups, Monitoring, History, Alerts

If you’re a fan of our HTTP/S lookup tools, you may have noticed that we added a new feature: Screenshots. Now, when you run an HTTP or HTTPS lookup on a domain you will see a screenshot of what the domain looked like when we ran the test.  If there is an error, you now have more information on what error may have occurred.



For example: if your server was down when running the test you will see a screenshot of what your customers saw as well as any error codes.

We’ve also added this same capability to our monitoring system!  Now, when we verify your server or website is down, we will include a screenshot  in the alert notification we send you. You get a snapshot of what your customers see when an outage occurs.  Over nights and weekends, on-call teams will be able to directly see what is going on right away and make the best triage decision for the alert.

In addition, monitoring customers can also access a historical screenshots for HTTP/S monitor outages.  Whenever we capture and verify a transition event, UP or DOWN, we store the screenshot in your monitor history.  Now, you will always have a view into site performance and customer experience!

Explicit search parameters now displayed in MxWatch Monitoring

If you have a large number of monitors and wanted to find them quickly, you’ve probably used our search field, and been a little frustrated…  You could search, but it was difficult to see what parameters were in effect, sometimes even hiding monitors you knew were there.  

We decided to improve search for you.  Now, when you enter search parameters, we explicitly display your search criteria and allow you to refine your searches by removing them individually.  Whether is is a name, a type, a tag name, or other search option, it is in the Search Parameter display.

For example if you are looking for all HTTP monitors that contain the word example, you will now see both http and example displayed as search parameters on your dashboard. With this new feature you can quickly see what search parameters have been applied to your monitors.

Domain Blacklist vs Domain Health – What’s the difference?

MxToolbox offers two products with Domain in the name and that sometimes causes a bit of confusion with our newer customers.  I’d like to take a few moments and compare and contrast the two products to eliminate confusion and you using the right product.

Domain Blacklists

A Domain Blacklist lookup takes a domain name as the argument and does the following:

  1. Looks up the A record for the domain to get the primary domain IP address
  2. Searches over 100 IP-based blacklists for this IP address and reports the results
  3. Searches a set of domain blacklists for the domain name and reports the results

This search will tell you what blacklists your web server is on and what domain blacklists your domain may have been added to, essentially giving you an idea of your domain’s public reputation.

IP Blacklists vs Domain Blacklist

IP blacklists contain the IP addresses of known spammers, malware infectors, virus and botnet distributors and other bad actors.  When an IP is on a blacklist it is has been caught in some bad act.  Since an IP address identifies a particular server somewhere, you know that the server is performing some bad act.

Domain blacklists contain a list of domain names that have been included in known spam attempts.  This does not mean that the domain is the source of the spam, or that the server is a source of spam.  It only means that the domain name or domain URL was included in spam or malware laden emails.

So, if you are sending email, you want to check the IP address of your mail server.  If you are running a web server, you want to check the IP address of the server.  If you are concerned about your domain’s reputation, you should check your domain against a domain blacklist.

Domain Health Lookup

A Domain Health Lookup takes your domain name and provides you with a battery of tests to judge the health of all aspects of your domain:

  • Blacklist status of Mail Server, Web Server and Domain
  • Status of your Mail Server and compliance with RFCs and best practice configuration (DMARC, DKIM, etc).
  • Status of your Web Server, including HTTPS Secure Certificate and setup compliance with RFCs
  • Status of your DNS and RFC compliance

So, a Domain Health test provides everything that a Domain Blacklist lookup provides plus a comprehensive look at the health of your domain.  

Use Cases

For simply finding your Domain’s online reputation, use a Domain Blacklist lookup.  To get an early warning on changes to your domain’s reputation, use a Domain Blacklist Monitor.  

To get comprehensive information on your domain, use Domain Health.  To get comprehensive monitoring on your entire domain: web, email, dns and reputation, use a Domain Health Monitor.


GoDaddy DNS – Or other slow DNS responders


Within the last few weeks, we’ve seen a spike in customers reporting that DNS monitors are “falsely” showing hosted DNS as DOWN.  Subsequent discussions with customers and their discussions with agents reveal that DNS services are technically UP but occassionally resolving in greater than 3 seconds.  This is a problem we find with other DNS providers from time to time, but seems to be a larger issue recently.

Our Philosophy

MxToolbox philosophy is that DNS resolution should be less that 3 seconds at all times.  We think of it this way: If your customers are looking for your site, they shouldn’t be waiting for 3 seconds plus the page load time of your site before they get to see your brand.  Instead, DNS should always resolve fast enough so that your customers find your site quickly.  Would you really want your customers’ first impressions to be that your systems are slow?  Neither would we.

So, what’s the solution?

Our experts have been thinking and discussing the issue and we came up with a couple of options:

  • Keep Monitoring – When your DNS is slower than 3 seconds, we will alert you. You should know that your performance is slow for your customers.  
  • Keep Talking to your DNS hosting provider – When they’re slow, let them know.  Only your provider can improve their performance.
  • Consider other options – If you regularly find your DNS resolving slowly, perhaps it’s time to upgrade to a better DNS hosting solution.
  • Set a filter – MxToolbox monitoring includes customizable filtering options in the Notifications Policy Page.  You could setup a Policy to require two or more warnings in a row before alerting you, to delay the alert or to suppress the alert entirely.

Regardless of the direction you take with your DNS, know that MxToolbox is here to support you with expertise in networking, email, web and everything else you need to keep your business up and running on the internet.

About MxToolbox offers free tools and paid monitoring packages to small, medium and large enterprises worldwide.  Our monitoring packages enable business to know immediately if a common networking, blacklisting or system performance issue occurs.  No other company provides such a comprehensive suite of solutions that can scale from small business to a service provider with hundreds of thousands of IP addresses.


Everything is New!  Okay, not everything but quite a few things…  You might have noticed that in the last 6 months we have added a number of new lookups, monitors and premium monitors.  Here’s a brief list to refresh your memory:


New features in the Professional interface.

With all the new features, we decided we needed to share the good news.  So, we’ve added a way that everyone can see our new features as we add them.  Clicking on “New!” either on the “More” Tools page or in the Professional interface will give you access to a list of tools we added in the last 90 days.

DNS Batch Tool

Have you ever needed to lookup DNS on a large list of IPs?  How about parsing a security log to see where a potential threat is coming from?  Combing through the log and getting the full list of IPs can be tedious and tiresome.  And, then you still have to run the DNS checks one-by-one or write a script to do it for you.

Or, you could come to MxToolbox where we have all the cool tools…

That’s right, we’ve launched a DNS Batch Lookup Tool that does all that for you.  Available to all MxToolbox Professional users, DNS Batch Tool eliminates the time-consuming work of parsing text for IP addresses and repetitive DNS lookups.

You can find it on the main menu of the MxToolbox Professional interface* along with our premium monitors like DNS Zone Protect and MailFlow Monitoring.


DNS Batch Tool provides takes simple text as the main input.


As, you can see below, I’ve copied an entire email into the tool so I can see lookup routing information for my most recent campaign.  I could also use security logs or a pre-generated list of IP addresses.


DNS Batch Tool parses the text file and automatically extracts all the IP addresses.



Processing these IP addresses yields reverse host name, country, region and city information, AS number and AS name.
