Maxaa loo isticmaalaa tan? Diiwaanka DNS-ka ee caadiga ah wuxuu magaca domain-ka ku sawirayaa cinwaanka IP-ga, halka diiwaanka PTR ee aagga Reverse DNS (rDNS) uu cinwaanka IP-ga ku sawirayo magaca domain-ka.
Waxaa ugu horreyn loo isticmaalaa in lagu xaqiijiyo server-yada boostada (sida cabbir ka dhan ah spam) iyo in lagu xaqiijiyo sax ahaanshaha martigeliyaha.
Si aad wax uga beddesho diiwaanka PTR, u gudub guddiga xakamaynta server-ka, dooro server-ka loo baahan yahay, ka dibna fur qaybta "Cinwaanka IP".
Kadib, dooro cinwaanka IP-ga ee loo baahan yahay oo guji "Tafatir".
Marka xigta, sheeg magaca domain-ka oo keydi isbeddelada.
Waa la dhammeeyay. Isbeddelladu waxay dhaqan geli doonaan dhowr saacadood gudahood.
Haddii wax isbeddel ah aan la arki karin maalinta labaad, fadlan la xiriir taageerada farsamada.
