The whole notion is one of Jan.Gr->expediency of configuration. Whois and domain registration still list Jan.Gr->two nameservers (primary and secondary) because it attempts redundancy Jan.Gr->(that's why two): the primary and secondary distinction there Jan.Gr->was initially kinda intended to reflect that people would run their own Jan.Gr->nameserver for a domain (the primary) and get somebody else offsite to Jan.Gr->host the secondary. Jan.Gr-> Jan.Gr->Your machine will query the nameservers listed in /etc/resolv.conf in Jan.Gr->order when it attempts to resolve a DNS query (ie, punting the question Jan.Gr->to a named somewhere). Jan.Gr-> Jan.Gr->named itself will pick a NS for a remote domain Jan.Gr->out of the list of NSs for that domain, for each query: each remote NS Jan.Gr->will be hit 1/n of the time (roughly), where there are n remote NS for Jan.Gr->that domain. Jan.Gr-> Jan.Gr->As clear as mud..? Jan.Gr-> .......... Thanks, I do have a question though. "IF" one is running BIND on their machine, acting as a "master" for their own domain (intenal 192.168.x.x network), can they keep they 2nd and 3rd stanza's as follows: search mydomian.com # current local domain nameserver 0.0.0.0 # current machine it's own master. nameserver 123.123.123.123 # standard secondary nameserver 111.111.111.111 # standard tertiary -- Bill Schoolcraft PO Box 210076 -o) San Francisco CA 94121 /\ "UNIX, A Way Of Life." _\_v http://forwardslashunix.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
