Should IP addresses show next to the DNS info?

ip, dns

Hi,

I noticed that for most domains when you do a whois lookup it will display the IP addresses next to the name servers.
However, when I do a whois lookup for our site, it only shows me the name servers. Is there any advantage of having the IP numbers next to the name servers?

Welcome to WebmasterWorld fello!

Hmmm... I looked at 10 domains and all include an IP. Whois records seem to be returned from an administrative/contact info database and I suspect there is no need for an IP here, but I'm not 100% certain...
Anyone?

It depends on the registrar, what information they store in their registry (and what then gets displayed in a reply on a whois request).
My own domains: mydomain.NET registered by netsol/verisign shows the nameservers' IP addresses, mydomain.ORG registered elsewhere does not. It doesn't really matter. The IP addresses can easily be looked up through DNS. However, directly addressing a plain IP address without doing a lookup would be faster ...
