You can host companyuk.com DNS zone on your internal DNS sever and create a record for WEB with internal IP address.

The short answer is yes. You need to have a zone for web.companyuk.com on your internal DNS servers. Then, you'll need to ensure that you have the host (A) record(s) created that point to the internal IP address. However, one important point. As soon as you put web.companyuk.com (and thus, companyuk.com) on your internal DNS servers, internal users will no longer be able to resolve any hosts that are not specifically listed in the zones. Whereas today, they are resolving all hosts listed in the external zone. Today, it sounds like you have one set of DNS servers for external which host companyuk.com. And you have one set of DNS servers for company.com. Let's assume you have 3 host records in companyuk.com: host1 at x.x.x.x (public IP) host2 at x.x.x.y (public IP) host3 at x.x.x.z (public IP) If you had companyuk.com to your internal DNS servers (residing side by side with the company.com zone), you must add all 3 of those host records to your internal zone (even if your only intention is to alter the behavior of one of the host records). In your case, if you want clients to continue to use the public IP for host2 and host3, you might add host1 internally and point it to the internal IP while adding host2 and host3 to match what they are on the external DNS servers. The end result of this proposed configuration is what many call split DNS (a single zone hosted internally with one set of records while also hosted externally [records may or may not be the same]). Hope that helps. Brian

Hi, "Problem" with hosting your external domain is than you have to create and maintain all records associed with it...http://blog.simaju.fr - Partage de connaissances et retour d'expriences.

Good afternoon. Would someone be kind enough to assist me with a DNS query? My public domain name is "companyuk.com" and my internal domain name is "company.com" I have a webserver on the public domain called "web.companyuk.com" which is called "web.company.com" internally on the local domain. Accessing the internal name internally and the external name externally works absolutely fine without problem. Is there anyway I can get clients from my LAN to use the external name "web.companyuk.com" and have it resolve to an internal address within "company.com"? Any assistance is greatly appreciated.

Hello, you can proceed like that: Create a primary DNS zone named web.companyuk.com Create an empty A record that points to the private IP address of the web server Once done, make sure that your client computers points to the correct DNS server and then use nslookup to check that all is okay.
