Run command &gt;ci.CityB.mo.us <br />
<br />
Check which IP you get for above internally<br />
<br />
Then check the domain name zone file here: <a href="http://www.kloth.net/services/dig.php" rel="ugc">http://www.kloth.net/services/dig.php</a><br />
<br />
This will tell you whether those A records are hosted externally

Yes it displays an outsie IP when I ping it. &nbsp;It doens reply but it resloves to an outside source. &nbsp;Funny I am abble to go to the browser and type <a href="http://ci.CityB.mo.us" rel="ugc">http://ci.CityB.mo.us</a>&nbsp;without www. and then it comes up now. &nbsp;That still doesnt seem right and feels like it is within but maybe it is them having issues.

We recently changed ISP providers. &nbsp;Im having an internal issue now that I think we had in the past but cant remember how we corrected. &nbsp;Internally, our domain is CityA.mo.us. I cannot get to the webpage of another city when I type the address ci.CityB.mo.us.<br />
<br />
Its obviously a DNS issue. &nbsp;Is this at the provider level or is there something I need to have internally on my dns server to push out.

DNS related to same domain

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
