> Thanks, this finally looks like what I need. it won't work. something like the code i posted is needed. for ptr resolution, /net/dns requires the numeric ip address, reversed, with ".in-addr.arpa" appended. also, the address read back from /net/dns is not the straight domain name (but you'll find that out soon enough).
documentation on /net/dns is not great. if one knew more about DNS, maybe the .in-addr.arpa thing would be obvious...
