Amakheli e-DNS ngamanye amakheli asetshenziswa isistimu yokusebenza ukuxhuma kwenye ikhompyutha. Lokhu kubalulekile ngoba akugcini ngokusheshisa ukuxhumana namanye amakhompyutha, kepha uma kwenzeka kuba nephutha, uhlelo olusebenzisayo lusebenzisela ukugcina uxhumano lukhona manje.
Ngokuzenzakalelayo, ukuxhumana kwethu kwe-adsl kufaka dns iWindows yethu ezowasebenzisa uma kwenzeka iphahlazeka noma iphutha, kepha uma kungamakheli kunethiwekhi efanayo, lapho kunephutha kukheli le-IP, kuzoba khona nephutha kukheli le-DNS. Kungakho amakheli e-dns evamise ukuguqulwa amanye asebenza ngokulinganayo futhi angumshwalense wokuwa noma kwezehlakalo ezingalindelekile.
Ukuze sikwazi ukushintsha amakheli e-DNS kufanele siye kuzakhiwo zedivayisi yeNethiwekhi, okungukuthi, ukumiswa kwekhadi lenethiwekhi. Lokhu sizokuthola ku- Iphaneli Yokulawula -> Inethiwekhi. Ezakhiweni zedivayisi sizothola izinketho eziningi, kufanele sikhethe i-Internet Protocol TCP / IPV4 bese uchofoza inkinobho Yezakhiwo. Lokhu kuzovula iwindi elingunxande elinezingxenye ezimbili. Engxenyeni engenhla sizoguqula ikheli le-IP kuthi engxenyeni engezansi ikheli le-DNS.
Ikheli le-IP aliphoqelekile ukuthi liguquke, ngaphezu kwalokho, uma uliguqula, ungashiywa ungaxhunyiwe ku-inthanethi njengoba ikheli lenethiwekhi lomhlinzeki wakho we-ADSL lingajwayelekile. Kepha ikheli le-dns lingashintshwa ngaphandle kwenkinga. Ngakho-ke simaka inketho engezansi ukunika amandla ibhokisi lekheli le-dns bese ufaka ikheli elisha. Manje sicindezela inkinobho Ok bese sivale amanye amawindi, ngalokhu sesivele sishintshe ikheli le-dns lethimba lethu.
Ukushintshwa kwekheli le-dns kuyinto elula kakhulu futhi ezimweni eziningi kungasivumela ukuthi sithuthukise ukuxhumana kwethu kwenethiwekhi kakhulu, inqobo nje uma sikhetha iseva enamandla yamakheli e-dns. Kunoma ikuphi, ukuze lokhu kwamuva kwaziwe, kufanele sinake izinto eziningana ngaphezu kwamakheli e-dns.
