A school I help recently had to change fixed ip addresses on their DSL line at Verizon. When they somehow found someone at Verizon who could remap the existing domain name to the new fixed ip address, that someone changed the mx records associated with the domain name to point to a hosted email server. This needs to be reset, and I was told by someone deep in the bowels of Verizon to talk to the manager of our domain name. They told me they don't do that stuff and that it needs to be changed in "bigguy.gte.net", which, I guess, is the authority for this record. Does this make sense, and if so, does anyone know who to contact that can do this?
