reverse DNS lookup on iRule

Thank you for the response. I tried the irule and I did not get the resolved name. I logged the client IP

 

 

when HTTP_REQUEST {

 

Hold HTTP data until hostname is resolved

 

HTTP::collect

 

log local0. "client ip = [IP::client_addr]"

 

Start a name resolution on the hostname

 

NAME::lookup [IP::client_addr]

 

}

 

when NAME_RESOLVED {

 

log local0. "client name = >[NAME::response]<"

 

 

Release HTTP data once hostname is resolved

 

HTTP::release

 

}

 

and the log shows

Jun 11 15:32:39 tmm tmm[1788]: Rule dns-name-lookup : client name = ><

 

 

I have the correct DNS configured on the bigIP. When I do a manual nslookup using that DNS server, it gets resolved.

 

 

Any ideas?
