DNS and ISPs

October 4th, 2007

You'd think that running a domain would be easy once you have the proper entries in your registrar's DNS server, but it is sometimes more difficult than you can imagine. For example, I recently had a lease expire on a DHCP address I grab from my ISP, and subsequently needed to update the glue records for my DNS information. Not a big change, just flip the IP in an A record from the old to the new.

My registrar seems to not know how to test that their DNS is correct, or doesn't care as I was required to scour machines looking for one that did not already have a DNS server that had cached the response, and make sure that the glue record had been updated successfully. I should not have to provide step-by-step instructions on how to do systems administration tasks to my providers; I will provide them as a courtesy so that no miscommunication occurs, but I should not need to provide them.
