Diagnosing Problems With Custom Domains: An Alternative Dig Tool

As I wrote earlier, when I'm diagnosing a problem with a custom domain - and occasionally, with other blog and network problems - my most frequently used tool is a Kloth online Dig. With Dig being an important diagnostic procedure, it's a good idea to have more than one Dig utility available.
  • The Kloth server may be down.
  • The Kloth server may not offer the right options.
  • It's good practice to occasionally (and sometimes, intentionally) cross check results against another server.

For many Dig investigations, I like to use a second online Dig service - WhoIs, provided by All-NetTools. The All-NetTools WhoIs Dig actually provides more than a standard Dig. A WhoIs Dig, for a domain, provides much valuable information about the domain / registrar relationship. Here, for instance, we can see an All-NetTools WhoIs Dig for this domain,


Domain Name:

Registrar: GODADDY.COM, INC.
Whois Server:
Referral URL:
Status: clientDeleteProhibited, clientRenewProhibited, 
clientTransferProhibited, clientUpdateProhibited

Expiration Date: 2010-03-24
Creation Date: 2008-03-24
Last Update Date: 2009-05-01

Name Servers:

Here, we see useful information about this domain, including the fact that it expires within the month. In cases where the domain in question is seen to be parked, knowing that a domain recently expired helps us advise a blogger that it's necessary to contact the registrar immediately, and avoid loss of domain registration.

A an All-NetTools DNS Dig against provides still more interesting and useful information.

The WhoIs SOA Dig shows us the SOA record.
Name Server
Email   (masked)
Serial Number  2009121603
Refresh  8 hours
Retry   2 hours
Expiry   7 days
Minimum  1 day

Here, we see the name of the domain master server, and the various expiry times for the domain.

The Whois DNS Dig shows us the well known host records.
Record  Type   TTL  Priority  Content  CNAME  1 hour   A  1 hour (Mountain View, CA, US)   A  1 hour (Mountain View, CA, US)   A  1 hour (Mountain View, CA, US)   A  1 hour (Mountain View, CA, US)   MX  1 hour  10   MX  1 hour  20   MX  1 hour  30   MX  1 hour  40   MX  1 hour  50   NS  1 hour   NS  1 hour   NS  1 hour   NS  1 hour   SOA  1 day 2009121603 28800 7200 604800 86400  CNAME  1 hour

This will never replace the Kloth Dig log, completely. The Kloth server offers many more options, such as the ability to selectively Dig against aliases besides the domain root and well known aliases. It is a worthy complement to a Kloth Dig in many cases, and can be used as a backup or cross check.

Your problem is your DNS address setup.
