FREE Domain and Mail Server Health Check
The Domain Name System (DNS) is without a doubt one of the most important components of a funcitoning internet. Without it, we would have to remember IP addresses (like phone numbers) to bring up web sites, email wouldn’t exist as it is now, and life would just be plain difficult.
For years I have been using many tools to test and verify validity of domain’s and domain servers for our own internal use and for our clients.
It’s amazed me the number of times that I have found moderate to major faults with the way some domains are set up in their DNS servers.
One of my favorite tools is DNSReport from DNSstuff.com. It is a very thorough look at how a domain name is configured in the DNS, and it will raise issues from core setup, to mail (MX), to web configuration.
There are a heap of other tools including Realtime Blacklist (RBL) monitoring, whois lookups etc etc
I consider their yearly fee’s somewhat expensive, but I can atest to their value.
