Nws tuaj yeem tsim los ntawm cov tsiaj ntawv, lej, thiab hyphens. Ntev - los ntawm 2 mus rau 63 cim. Cia wb mus saib txhua yam kom ntxaws ntxiv.
internet ua haujlwm li cas? Domain: Txhais
Txhua lub computer muaj tus IP. Nws muaj qee txoj hlua ntawm tus lej. Txhawm rau nrhiav cov peev txheej hauv Is Taws Nem, koj yuav tsum paub qhov chaw nyob ntawm lub server uas nws nyob.
Ntau qhov chaw sib txawv tuaj yeem nyob ntawm tib lub server tib lub sijhawm. Txhawm rau pab txhawb kev tshawb nrhiav, ua kom pom tseeb rau tib neeg, tsim lub npe sau npe (tshwj xeeb los ntawm lus Askiv DNS - Domain Name System).
