Advanced Link Sharing

10th March 2010

A great new feature has been added to whatsmydns.net today, it's a feature that I have been meaning to add for quite some time now but I received an email from a user a few days ago asking for more or less the exact feature I had in mind so I figured that many other people out there would benefit also so I decided it was time for it to be implemented.

whatsmydns.net now supports advanced linking so that you can more easily share links with your friends, coworkers, or people helping you out on a community forum or similar. The way it works is very simple and does not change the way that the site works in any way. There are 2 important changes to the site.

  1. Whenever you perform a search to check DNS propagation the fragment portion of the URL (the bit after the #) will be updated with your search query. This is the link that you will need to share with people.

  2. You can now access the site with the links that have been shared from the above step by simply going to the URL and when the page loads it will automatically perform the DNS propagation search specified in the link.

I hope that many people find this a great addition to the functionality of the site and that it helps out people when sharing links online to whatsmydns.net

What's My DNS Design Update

24th February 2010

whatsmydns.net has had a major design update today! Since the website started out it has more or less looked very much the same with the odd graphic change here and there along with a few different main header images.

whatsmydns.net has grown substantially since its initial release and now contains many more pages and therefore a design overhaul was needed. The changes made to the site should give the user a much nicer browsing experience both in terms of looks and navigation additions.

I hope that as the site continues to grow that I will be able to keep adding great features while maintaining a great overall look and feel.

Thanks to all those who have supported the site as its grown and I look forward to adding new features in the future.

Below is the list of the servers that have been added to the database:

DNS Checks for Red-Green Color Blind

5th September 2009

Just a quick update to the status markers used to show the state of DNS propagation on the main whatsmydns.net home page, these changes have been made due to the request of users who were having trouble distinguishing which DNS servers had propagated and which had not due to color blindness.

New DNS status markers:

Old DNS status markers:

I hope this change helps where it is needed, the feedback so far has been very good.

What's My DNS New Banner Image

1st September 2009

A little cosmetic update to the website today, as you may have noticed we have a brand new banner image across the top of each page on What's My DNS. This new banner shows at a glance what the website is about so that new visitors will quickly gain a better understanding of the service we offer - which of course is checking the current state of DNS propagation around the world. Of course on top of that it just looks much nicer than the old one so that's a bonus.

For reference purposes here is the old banner:

DNS Server Database

30th May 2009

As the site continues to grow, more features are being added into the system - in the near future there will be a database of DNS servers for a range of different ISP's around the world. This will be an excellent resource for people who are trying to find their local DNS servers in order to configure their Internet connections. Just to get things started I have added Exetel DNS Servers and aaNet DNS Servers. In the future the system will be expanded to allow user submitted data so that the database can grow much larger.

DNS Record Type Updates

26th June 2008

A bunch of new features have been added to What's My DNS today, the most important and requested is the ability to perform lookups on different record types. The following DNS record types are now suppored:

  • A - Host address (dotted quad)
  • AAAA - IP v6 address (address spec with colons)
  • CNAME - Canonical name for an alias (domain name)
  • MX - Mail exchanger (preference value, domain name)
  • NS - Authoritative nameserver (domain name)
  • PTR - Domain name pointer (domain name)
  • TXT - Descriptive text (one or more strings)

As usual, let me know if there's any problems with these new additions. It's probably worth mentioning that when doing a lookup on your MX record, make sure you're only using the part of the domain that you receive email from. For example if you receive email at [email protected] then enter example.com into the input box not www.example.com (as that would be the email address for [email protected] and is probably not configured to have a MX record).

I have also started writing a bit of reference material in order to hopefully help people out with various DNS tools for the operating system they are running. At the moment I have only really touched on the Flush DNS page and DNS Tools page, but there will be more to come shortly.
