Check out the list of official mirrors,

You'll also need to resolve the mirror names to addresses and use those since there is no dns working at that point of the install. For example, the mirror I use is mirror.mcs.anl.gov, but I needed to use its IP address, 140.221.9.138.
The ftp install readme has all you need,
ftp://ftp.suse.com/pub/suse/i386/current/README.FTP
