Strangely, about 20 computers here are called "localhost." True, they have other names too, in some cases several other names. remember that IP address and therefore host names belong to Interfaces, not Hosts. There's no limit to the number of names a computer can have. Have fun with this one (which I found by typo): summer@thylacine ~]$ host localhost.cds.nerseine.nu localhost.cds.nerseine.nu has address 212.181.91.6 localhost.cds.nerseine.nu has address 69.25.75.72 [summer@thylacine ~]$ host localmast.cds.nerseine.nu localmast.cds.nerseine.nu has address 69.25.75.72 localmast.cds.nerseine.nu has address 212.181.91.6 [summer@thylacine ~]$ host bereft.cds.nerseine.nu bereft.cds.nerseine.nu has address 69.25.75.72 bereft.cds.nerseine.nu has address 212.181.91.6 [summer@thylacine ~]$ -- Cheers John
