toto je hlaska squidu. asi na lokalnom stroji mas v hosts tabulke definovany
stroj "proxy" ale nie na masine kde bezi squid. Alebo pouzivas rozlicne DNS
servre.

ano.

skus nastavit append_domain.

@ znamena v zapise bindu aktualny ORIGIN, t.j. domenu ktoru prave definujes,
pokjial si nenastavil iny origin direktivou

$ORIGIN nieco.tutam.sk.

prva bodka sa nahradi zavinacom a dostanes mail adresy osoby zodpovednej za
tu zonu - root na tutam.sk
