I make very little use of short hostnames. re whether I should be trying to change my domain from pacbell.net to sbcglobal.net: i get response from "shieldsup": ---------------- "Your Internet connection's IP address is uniquely associated with the following "machine name": ppp-71-xxx-xx-xxx.dsl.snfc21.pacbell.net The string of text above is known as your Internet connection's "reverse DNS." The end of the string is probably a domain name related to your ISP. This will be common to all customers of this ISP. But the beginning of the string uniquely identifies your Internet connection. The question is: Is the beginning of the string an "account ID" that is uniquely and permanently tied to you, or is it merely related to your current public IP address and thus subject to change?..." ------------------ for that quad number: first two numbers i think remain the same, but the last two change periodically. How often I don't have enough data to say. For me pacbell.net is "probably a domain name related to your ISP" It then seems ok, maybe unnecessary?, that I use "DOMAIN=pacbell.net" in my ifcfg-eth0. And I will drop the idea of trying to change domain from pacbell.net to sbcglobal.net FWIW, NM-created resolv.conf: [byers@f12 f12]$ cat /etc/resolv.conf # Generated by NetworkManager search pacbell.net nameserver 206.13.31.12 nameserver 68.94.156.1 [byers@f12 f12]$ doesn't use both "search" and "domain", consistent with your advice thanks Jack -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
