Kule meko, "ufanelekile" uthetha "ochaziweyo" kuba indawo epheleleyo ye-domain ichazwe egameni. I-FQDN icacisa indawo ekhoyo yombutho ngaphakathi kwi- DNS . Ukuba igama alilona elikhankanyiweyo, libizwa ngokuba negama le-domain elifanelekileyo, okanye iPQDN. Kukho ulwazi oluninzi kwi-PQDN phantsi kweli phepha.
I-FQDN inokuthiwa yigama elingumgama elipheleleyo kuba libonelela indlela epheleleyo yomphathi.
Imizekelo yeFQDN
Igama le-domain elifanelekileyo lihlala libhalwa kule fomethi: [igama lomphathi] . [Domain] . [Tld] . Umzekelo, i-imeyile iseva kummandla wesibonelo.com ungasebenzisa i- imeyile yeFQDN.example.com .
Nazi ezinye zeempawu zamagama wesiqhelo ezifanelekileyo:
www.microsoft.com en.wikipedia.org p301srv03.timandtombreadco.usAmagama wesiGama "awanako ukufaneleka ngokupheleleyo" aya kuhlala enokungacatshulwa ngabo. Umzekelo, i- p301srv03 ayikwazi ukuba yiFQDN kuba kukho nayiphi na imimandla yimizi enokuthi ibe nomncedisi ngeli gama. i-p301srv03.wikipedia.com kunye ne-p301srv03.microsoft.com imimiselo emibili nje kuphela - ukwazi ukuba igama lomninimzi alinakunceda kakhulu.
Kwaye i-microsoft.com ayifanelekanga ngokugcweleyo kuba asiyazi ngokuqinisekileyo ukuba yintoni igama lomninimzi, nokuba ngaba ezininzi iiphequluli zicinga ngokuzenzekelayo yi- www .
Amagama esi siko angabhalwanga ngokugcwele ngokwenene abizwa ngokuba ngamagama asemgangathweni. Icandelo elilandelayo linolwazi olungaphezulu kwi-PQDNs.
Qaphela: Amagama ekwi-domain efanelekileyo afanelekileyo ayifuna ixesha ekupheleni. Oku kuthetha www.microsoft.com. kuya kuba yindlela efanelekileyo yokungena kwiFQDN. Nangona kunjalo, ezininzi iinkqubo zivele zithetha ixesha elide nokuba awukunikezi ngokucacileyo. Ezinye izikhangeli zewebhu zinokukuvumela ukuba ufake ixesha ekupheleni kwe- URL kodwa akudingeki.
Igama elinguQinisekiso leGama eliQinisekayo (PQDN)
Elinye ixesha elifana neFQDN yi-PQDN, okanye igama elithile eliqhelekileyo le-domain, elinegama nje kuphela elingasichazwa ngokupheleleyo. Umzekelo we- p301srv03 ovela ngasentla uyi-PQDN kuba ngelixa ulazi igama lomninimzi, awukwazi ukuba yeyiphi i-domain.
Amagama aseburhulumenteni abafanelekileyo afanelekileyo asetyenziswa nje ngokulula, kodwa kuphela kwiimeko ezithile. Ziye zenzelwe iimeko ezizodwa xa kulula ukubhekisela kwigama lomninimzi ngaphandle kokuchaza igama elipheleleyo le-domain elifanelekileyo. Oku kunokwenzeka kuba kulawo mxholo, idibansi isele yaziwa kwezinye iindawo, kwaye ke igama kuphela lomninzi lifunekayo kumsebenzi othile.
Ngokomzekelo, kwiirekhodi zeDNS, umlawuli angabhekisela kwigama le-domain egqibeleleyo njenge-en.wikipedia.org okanye uyifutshane kwaye usebenzise igama lomncedisi we- en . Ukuba kuncishiswe, yonke inkqubo iya kuqonda ukuba kuloo mongo othile, enokubhekisela ku-en.wikipedia.org .
Nangona kunjalo, kufuneka uqonde ukuba i-FQDN ne-PQDN ayiyiyo into efanayo. I-FQDN inikeza indlela epheleleyo ye-host host ngenkathi i-PQDN inikezela igama elizalanayo eliyingxenye encinane yegama elipheleleyo lesizinda.
