Iseva ye-resolver ye-DNS ivumela ikhompyutha (okanye umntu) ukuba ikhangele igama le-domain (okt) kwaye ifumane idilesi ye-IP yekhompyutheni, iseva, okanye enye idivaysi eyayiyo (okt 207.241.148.80). Cinga ngesombululo se-DNS njengencwadi yefowuni yeekhomputha.
Xa uthayipha igama le-domain yewebhusayithi kwisiphequluli sakho sewebhu, emva kweembonakalo, iseva ye-resolver ye-DNS ekhompyutheni yakho ekhombayo isebenza ukucinga ezinye iiseva ze-DNS ukucacisa idilesi ye-IP egama lesizinda "isombululo" ukuze isiphequluli sakho Unokuya kwaye ufumane nayiphi na into oyikhangela kuyo loo ndawo.
