Ikheli lasesizindeni se-inthanethi yikheli lekhompyutha lapho ithrafikhi ye-inthanethi ilethwa khona. Kunezinhlobo ezimbili zamakheli e-IP - IP eguquguqukayo ne-static. Lapha kulesi sihloko, sixoxe ngakho konke mayelana nekheli le-IP elimile kanye nekheli le-IP eliguqukayo nokuthi ahluke kanjani komunye nomunye.
Uyini umehluko phakathi kwekheli le-IP elimile neliguqukayo?
Wonke umuntu osebenzisa i-inthanethi kufanele abe nolwazi olwanele mayelana nekheli le-IP. Hhayi-ke, sonke siyazi ukuthi kunento efana "nekheli le-IP". Kodwa bambalwa abaziyo ukuthi wenzani. Ukuba nolwazi olwanele mayelana nekheli le-IP kungakusiza ngezindlela ezimbalwa esizoxoxa ngazo kulesi sihloko.
Ngakho-ke, ake siqale ngekheli le-IP? Liyini ikheli le-IP? Nokho, ngamagama alula, ikheli le-IP yikheli ledivayisi exhunywe kunethiwekhi. Ikheli lasesizindeni se-inthanethi limane nje liyisihlonzi sedijithali esiyingqayizivele esinikezwe amadivayisi axhunywe ku-inthanethi. Ikheli lasesizindeni se-inthanethi lisiza ngokuhlukile ukuhlonza uxhumano ngalunye.
Ikheli lasesizindeni se-inthanethi yikheli lekhompyutha lapho ithrafikhi ye-inthanethi ilethwa khona. Manje nonke kungenzeka niyazibuza ukuthi ubani osinika ikheli le-IP. Nokho, bekuyi-ISP (Umhlinzeki Wesevisi Ye-inthanethi) ekunikeza ikheli le-IP lapho ubhalisa. I-ISP ivamise ukunikeza abasebenzisi ikheli le-IP elimile noma ikheli le-IP eliguquguqukayo elisuselwe ezidingweni.
Liyini ikheli le-IP elimile?
Ikheli le-IP elimile yilokho i-ISP yakho ekunika khona unomphela. Lokhu kusho ukuthi noma uqala kabusha ikhompuyutha yakho, ikheli le-IP lizohlala linjalo. Amaseva abamba amawebhusayithi, ahlinzeka ngemilayezo ye-imeyili, isizindalwazi, nezinsizakalo ze-FTP ngokuvamile zinikezwa ikheli le-IP elimile. Ngenkathi sikhetha i-ISP, ngokuvamile sithola ikheli le-IP elimile elingeke lishintshe kuze kube yilapho lishintshwa mathupha.
Kodwa, ikheli le-IP elimile ngokuvamile lingeleziphakeli futhi njengoba lingelakho, kuzodingeka ulungiselele ngesandla amadivaysi akho afana nomzila noma iseva ukuze usebenzise ikheli le-IP elimile. Nokho, ikheli le-IP lingafihlwa ngezinhlelo zokusebenza ze-Virtual Private Network (VPN).
Liyini ikheli le-IP eliguqukayo?
Ikheli le-IP eliguqukayo liphambene nekheli le-IP elimile. Ikheli le-IP eliguqukayo linikezwa ikhompuyutha ngumhlinzeki wakho wesevisi ye-inthanethi. Kusho nje ukuthi ngaso sonke isikhathi uma uqala kabusha idivayisi exhunywe ku-inthanethi, uzothola ikheli le-IP elihlukile.
Umsebenzisi we-telecom ngokuvamile usebenzisa ikheli le-IP eliguqukayo. Lesi isizathu esiyinhloko esenza ushintshe ikheli lakho le-IP njalo uma uqala kabusha idatha yethu yeselula. Ngobuchwepheshe, ikheli le-IP eliguqukayo lamakhadi enethiwekhi yekhompuyutha linikezwa ngokuzenzakalelayo kusetshenziswa iphrothokholi ye-DHCP njengoba ikheli le-IP eliguqukayo lishintsha ngokuzenzakalelayo kuye ngokucushwa kwe-DHCP.
Uma siqhathanisa kokubili i-IP emile neguqukayo, kubonakala sengathi i-IP eguquguqukayo ithembeke kakhulu uma iqhathaniswa ne-Static ngoba ilungiswa ngokuzenzakalelayo. Ngaphezu kwalokho, izingozi zokugebenga iwebhusayithi zihlala ziphezulu ku-IP emile ngoba ihlala imile.
Ngakho-ke, konke lokhu kumayelana nekheli le-IP elimile nelinamandla. Ucabangani ngalokhu? Yabelana ngemibono yakho kumazwana angezansi.
