- 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, nitecruzr.net.
http://www.who.is/whois/nitecruzr.net/ REGISTRY WHOIS FOR NITECRUZR.NET Domain Name: nitecruzr.net Registrar: GODADDY.COM, INC. Whois Server: whois.godaddy.com Referral URL: http://registrar.godaddy.com Status: clientDeleteProhibited, clientRenewProhibited, clientTransferProhibited, clientUpdateProhibited Expiration Date: 2010-03-24 Creation Date: 2008-03-24 Last Update Date: 2009-05-01 Name Servers: ns11.domaincontrol.com ns12.domaincontrol.com ns53.domaincontrol.com ns54.domaincontrol.com
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 nitecruzr.net provides still more interesting and useful information.
The WhoIs SOA Dig shows us the SOA record.
NITECRUZR.NET SOA RECORD Name Server ns11.domaincontrol.com 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.

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.
