Free DNS checks

A while ago, dnsstuff.org, the site I used to check everything related to DNS got off the freeware market and they started a paid service, which, no doubt is good, please pay for it if you still want to use them, but I want to give you a few alternatives.

Of course you have the shell command line tools like nslookup, dig and whois but those are not for the faint of heart, so below you have some online alternatives:

The first, is IntoDNS.com (which I wrote about here in January) does a full DNS checkup of a domain.

The ones who want more than this, can use dnsutils.org, which allows users to do the following:

  • Reverse DNS
  • Ping Host/IP
  • FQDN based DNS Lookup (A, AAA, SOA, CNAME, NS, MX)
  • CIDR Calculator
  • IPV6 Compression
  • IPV6 Expansion
  • RBL Lookup
  • transform IPv4 into binary and back
  • transform IPv6 into bin and back

Quite a good service offered by Jonas Genannt <jonas (AT) dnsutils (DOT) org>.

Enjoy!
