- Ukuxazulula izinkinga ezivamile ze-router DHCP

Ixazulula izinkinga ze-router evamile ye-DHCP

Isevisi ye-DHCP, noma i-Dynamic Host Configuration Protocol, idlala indima ebalulekile ekwabeleni ngokuzenzakalelayo amakheli e-IP kumadivayisi akunethiwekhi. Nokho, ngezinye izikhathi izinkinga ziyavela lapho kulungiselelwa i-DHCP. ye-routerNazi ezinye izixazululo ezivamile zezinkinga ongahlangabezana nazo:

1. Amakheli e-IP awanikezwanga ngendlela efanele: Uma amadivayisi kunethiwekhi yakho angawatholi amakheli e-IP asuka kumzila nge-DHCP, kungase kube nokucushwa okungalungile kumzila. Hlola ukuthi isevisi ye-DHCP ivuliwe yini nokuthi ububanzi bekheli le-IP elishiwo livumelekile yini futhi alidluleli neseva ye-DHCP. enye inethiwekhi. Futhi qiniseka ukuthi "ukunikezwa kwekheli le-IP" noma "ichibi lekheli le-DHCP" kulungiselelwe ngendlela efanele.

2. Izinkinga zokuxhumeka kwe-inthanethi: Uma amadivayisi axhunywe kumzila wakho nge-DHCP engakwazi ukufinyelela ku-inthanethi, kungase kube ngenxa yenkinga ngezilungiselelo zeseva yakho ye-DNS. Qiniseka ukuthi irutha yakho iwabela kahle amakheli eseva ye-DNS kumadivayisi axhunywe kumzila wakho. amadivayisi kunethiwekhiFuthi, qinisekisa ukuthi iseva ye-DNS okhomba kuyo ivumelekile futhi isebenza kahle. Ukuqalisa kabusha kokubili irutha yakho namadivayisi axhunyiwe kungaphinda kuxazulule izinkinga zokuxhumeka kwe-inthanethi.

3. Ikheli le-IP liyashayisana: Uma unamadivayisi ahlala enenkinga yokuxhuma noma uma uhlangabezana nokunqamuka kwenethiwekhi, kungase kube khona ukungqubuzana kwekheli le-IP kunethiwekhi yakho. Lokhu kungqubuzana kwenzeka lapho amadivaysi amabili noma ngaphezulu anekheli le-IP elifanayo elinikezwe umzila. Ukuze uxazulule lokhu, hlola izilungiselelo ze-DHCP kumzila futhi uqiniseke ukuthi ububanzi bekheli le-IP elitholakalayo banele. wonke amadivayisiUngakwazi futhi ukwabela amakheli e-IP amile kumadivayisi athile ukuze ugweme ukungqubuzana kwamakheli.

- Izincomo zokuthuthukisa ukusetshenziswa kwe-DHCP kumzila

I-DHCP (i-Dynamic Host Configuration Protocol) iyiphrothokholi yenethiwekhi evumela irutha ukuthi inikeze ngokuzenzakalelayo amakheli e-IP kumadivayisi axhunywe kunethiwekhi. Lokhu kuwusizo ikakhulukazi ezindaweni zenethiwekhi ezinamadivaysi amaningi, njengoba i-DHCP yenza lula futhi iqondise inqubo yokunikezwa kwekheli le-IP. Ngokusebenzisa ngokugcwele i-DHCP kumzila, ukusebenza kwenethiwekhi kungathuthukiswa nakakhulu.

Nazi ezinye izincomo zokwandisa ukusetshenziswa kwe-DHCP kumzila:

1. Lungiselela isikhathi sokuqashisa: Isikhathi sokuqashisa sisho isikhathi lapho idivayisi ingasebenzisa khona ikheli le-IP elinikezwe i-DHCP. Ukusetha isikhathi esifanele sokuqashisa kubalulekile ukuze ugweme izingxabano zamakheli e-IP kanye nokuthuthukisa ukusetshenziswa kwamakheli atholakalayo. Kunconywa ukusetha isikhathi sokuqashisa esihlangabezana nezidingo zenethiwekhi, ukugwema izikhathi ezimfushane kakhulu noma ezinde kakhulu.

2. Gcina amakheli e-IP: Uma kunamadivayisi kunethiwekhi adinga ikheli le-IP eligxilile futhi anganikezwa ngokuzenzakalelayo i-DHCP, ungasebenzisa ukubhukha ikheli le-IP. Lokhu kuzoqinisekisa ukuthi lawo madivayisi ahlala ethola ikheli le-IP elifanayo, okuwenza kube lula ukuwaphatha nokuwalungiselela. Ukubhukha ikheli le-IP kungalungiselelwa ngokusebenzisa isixhumi esibonakalayo sokuphatha somzila.

3. Qaphela futhi uphathe ukusetshenziswa kwekheli le-IP: Kubalulekile ukuba nokubonakala okucacile kwamakheli e-IP asetshenziswa kunethiwekhi. Lokhu kuzokuvumela ukuthi uthole futhi uxazulule izinkinga ikheli lokukhathala, kanye nokuhlonza amadivayisi angagunyaziwe noma angafuneki kunethiwekhi. Usebenzisa amathuluzi okuqapha namakheli e-IP, ungaqinisekisa ukusetshenziswa kahle kwe-DHCP futhi ugcine ukulawula kumadivayisi axhunyiwe.

Ekuphetheni, I-DHCP imele i-Dynamic Host Configuration Protocol kumzila. Le nqubo yomthetho ibalulekile kumanethiwekhi ekhompyutha, njengoba ivumela amakheli e-IP ukuthi anikezwe ngokuzenzakalelayo kumadivayisi axhunywe kumzila. Umsebenzi oyinhloko we-DHCP ukwenza lula ukuphathwa kwenethiwekhi nokwenza lula ukucushwa kwedivayisi. Ngokusebenzisa i-DHCP, abalawuli benethiwekhi bangagwema umsebenzi owenziwa ngesandla wokunikeza ngezibalo ikheli le-IP ngalinye kudivayisi ngayinye ekunethiwekhi, okungase kube inqubo eyisicefe futhi ethambekele kumaphutha.

Ngaphandle kwalokho, I-DHCP ivumela ukusetshenziswa kabusha kwamakheli e-IP kunethiwekhi, okuvumela ukusetshenziswa ngokuphumelelayo kwamakheli atholakalayo. Lokhu kuwusizo ikakhulukazi kumanethiwekhi amakhulu lapho kungase kube khona amakhulu noma izinkulungwane zamadivayisi axhunyiwe. I-DHCP iphinde inikeze izinketho zokumisa amanye amapharamitha enethiwekhi, njengamamaski e-subnet, amasango azenzakalelayo, namaseva e-DNS. Lokhu kusho ukuthi, nge-DHCP, kungenzeka ukumisa ngokuzenzakalelayo zonke izici ezidingekayo zoxhumano lwenethiwekhi. yedivayisi.

Nakuba i-DHCP isetshenziswa kabanzi futhi inenzuzo, I-DHCP futhi iveza izinselelo ezithile nokucatshangelwa. Isibonelo, ukungqubuzana kwekheli le-IP kungenzeka uma amadivayisi amabili acela ikheli elifanayo ngesikhathi esisodwa. Ukuze unciphise lokhu, amarutha ngokuvamile asebenzisa inqubo ebizwa ngokuthi ukuqashisa ikheli le-IP, lapho ikheli linikezwa isikhathi esimisiwe futhi livuselelwe ngezikhathi ezithile. Ukwengeza, i-DHCP ingase ingafaneleki izimo ezithile zokusetshenziswa, njengeziphakeli noma amadivayisi anokulungiselelwa okuqondile okuqondile.

Ngokufigqiwe, I-DHCP kumzila iyiphrothokholi ebalulekile yokwenza ukucushwa kwedivayisi kube lula kunethiwekhi. Ivumela ukunikezwa kwekheli le-IP okuzenzakalelayo, ukusetshenziswa kabusha kwekheli, nokucushwa kwamanye amapharamitha enethiwekhi. Nakuba iletha izinselele ezithile, i-DHCP isasetshenziswa kabanzi futhi inenzuzo ekuphathweni kwenethiwekhi. Ngokuqonda okuqinile kwe-DHCP, abalawuli bangakwazi ukuthuthukisa ukucushwa kwenethiwekhi nokusebenza ukuze baqinisekise ukuxhumeka okusebenzayo nokuthembekile.
