DNS Lookup

Playing with the following rule trying to get DNS lookups working. Every time I hit the rule the name::response allways comes back empty. Any ideas what I am doing wrong. Thanks     when HTTP_RE...

Aaron,

 

 

Here you go...

 

 

C:\>nslookup fmservices.ocfo.mycompany.com

 

Server: dnr-anycast.mycompany.com

 

Address: 117.142.8.122

 

 

Name: fmservices.gss.mycompany.com

 

Address: 117.142.8.140

 

Aliases: fmservices.ocfo.mycompany.com

 

 

 

If I run dig, I see the alias as a CNAME record. My understanding from the other team is this is done like this for their load balancer that offers up addresses (3DNS).

 

 

Prior to the CNAME record being added, NAME::lookup worked fine. Now I get nothing back in the address list.

 

 

Time to ask support?

 

 

Thanks,

 

 

Tom
