zone lookups for unresolved IPs

best way/database source to do this?

[amznVibe]

I'd like to do semi-realtime zone lookups in my entry logs for IPs that don't have rdns.

What is the best database to do lookups from (ie. zoneedit.com) and can I get some hints/snippets for the best way to do this in PHP?

example: http://www.zoneedit.com/whois.html?zone=134.6.32.10

unless they have some type of API then you will just have to parse the returned page to get your values.

Maybe take a look at curl [ca2.php.net]
