Of course it works on your machine because most likely you have an entry in the hosts file pointing your ip to your domain name or as you said you have set up DNS Records. However has the ISP or person whom you got the ip address from made the reverse records in his DNS pointing that ip address to your domain name? If not i guess you can see why other name servers cannot reverse your ip back to your name. The name server authoritative for the reverse of that ip class i.e xxx.xxx.IN_ADDR.ARPA should have that pointer record in order for other name servers to reverse your ip back to a name. You can check whether any reverse records exist by querying the name server that is authoritative by using dig like this dig @domain.name.of.authoritativeserver xxx.xxx.xxx.xxx.IN_ADDR.ARPA any where xxx.xxx.xxx.xxx.IN_ADDR.ARPA is your ip reverse . Then make necessary steps. -- Joseph Begumisa Uganda OnLine begj@eahd.or.ug ------------------------------------------------------------------------------- On Mon, 4 Dec 2000, greego barooke wrote: > > > ive setup a dns server,,, all was fine except for a reverse lookup > > when i try to lookup with an ip in another dns server, it will not display > the corresponding hostname of the ip. but in my server where i setup the > dns the reverse ip works,.. > > thanks > > > > - > : send the line "unsubscribe linux-net" in > the body of a message to majordomo@vger.kernel.org > - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
