http remote install + dns weirdness

Has anybody had a problem in doing remote installs in that giving the FQDN of the install server fails, but going by IP + the sources directory works, even though you point your host to a legit name server? (eg. 127.10.10.10/suse/install/directory (fake IP there obviously)) With http get on the network, you'll see it emitting stuff like: http://127.10.10.10/suse/install/directory/i586/libvisual-0.2.0-4.i586.rpm HTTP/1.1 I seem to remember seeing this in the past, and last night was reminded of it when someone did an install from a server I have here, and it gave him this problem initially. Ideas? D'Arcy
