Raspunsul NS-ului tau 193.231.242.2 este corect; www.as.ro are ca IP 127.0.0.1 pentru ca asa este configurat RR-ul: $ dig +short ns as.ro ns2.decknet.ro. ns1.decknet.ro. $ dig +short @ns1.decknet.ro www.as.ro 127.0.0.1 $ dig +short @ns2.decknet.ro www.as.ro 127.0.0.1 Probabil nu exista nici un website configurat pentru www.as.ro si prin urmare traficul catre acest hostname vide directionat catre 127.0.0.1. Este un config un destul de lame din partea hostmaster-ului zonei ar.ro deoarece vine in contradictie cu RFC 3330 [1] si RFC 1700 [2]. Ar fi mult mai corect sa nu specifice un AA RR pentru www.as.ro. [1] 127.0.0.0/8 - This block is assigned for use as the Internet host loopback address. A datagram sent by a higher level protocol to an address anywhere within this block should loop back inside the host. This is ordinarily implemented using only 127.0.0.1/32 for loopback, but no addresses within this block should ever appear on any network anywhere [RFC1700, page 5]. [2] Internal host loopback address. Should never appear outside a host. -- Digitally yours, Florin Iamandi (Slippery) Reason is the first victim of emotion. -- Scytale, Dune Messiah
