Lokho Okushoyo Uma Ubona Ikheli le-IP 0.0.0.0
Amakheli we-IP ku- Inthanethi Protocol (IP) inguqulo 4 (i-IPv4) ibanga kusuka ku-0.0.0.0 kuze kufike ku-255.255.255.255. Ikheli le-IP 0.0.0.0 linencazelo ekhethekile eziningana kumanethiwekhi ekhompiyutha. Noma kunjalo, ngeke isetshenziswe njengekheli ledivaysi yenjongo jikelele.
Leli kheli le-IP lihlelwe njengelinye elivamile (linendawo ezine zezinombolo) kodwa liyikheli kuphela lesibambiso noma elisetshenziselwa ukuchaza ukuthi ayikho ikheli elivamile elibelwe. Isibonelo, esikhundleni sokungena ikheli le-IP endaweni yenethiwekhi, 0.0.0.0 ingasetshenziselwa ukusho noma yini ukusamukela wonke amakheli we-IP noma ukuvimbela wonke amakheli e- IP kumzila ozenzakalelayo .
Kulula ukudidanisa u-0.0.0.0 no- 127.0.0.1 kodwa khumbula nje ukuthi ikheli elinamazombe amane linemisebenzi echazwe eziningana (njengoba kuchazwe ngezansi) ngenkathi i-127.0.0.1 inenhloso eyodwa ecacile yokuvumela idivayisi ukuthi ithumele imiyalezo ngokwayo.
Qaphela: Ikheli le-IP 0.0.0.0 ngezinye izikhathi libizwa ngekheli le-wildcard, ikheli elingacacisiwe noma i- INADDR_ANY .
Yini okungu-0.0.0.0 okushoyo
Ngamafuphi, 0.0.0.0. ikheli elingenakulungiswa elichaza i-invalid noma i-target engaziwa. Nokho, kusho okuhlukile kuye kuye ngokuthi kubonakala kudivayisi iklayenti njengekhompyutha noma kumshini wesiphakeli.
Kumakhompyutha weKlayenti
Ama-PC namanye amadivayisi weklayenti ngokuvamile abonisa ikheli le-0.0.0.0 uma engaxhunyiwe kwinethiwekhi ye- TCP / IP . Idivayisi ingase izinike lona leli kheli ngokuzenzakalelayo noma nini lapho ingaxhunyiwe ku-intanethi.
Kungase kubekwe ngokuzenzakalelayo yi- DHCP uma kwenzeka ukwehluleka kwesabelo sekheli. Uma isethwe ngaleli kheli, idivayisi ayikwazi ukuxhumana nanoma yimaphi amanye amadivayisi kuleyo nethiwekhi.
I-0.0.0.0 ingabuye ibekwe njenge- subnet mask edivaysi esikhundleni sekheli layo le-IP. Nokho, i-mask mask ne-value ayinayo injongo ewusizo. Kokubili ikheli le-IP ne-network mask ngokuvamile linikezwa 0.0.0.0 kumakhasimende.
Kuye ngendlela esetshenzisiwe ngayo, i-firewall noma isofthiwe ye-router ingasebenzisa 0.0.0.0 ukukhombisa ukuthi zonke ikheli le-IP kufanele livinjelwe (noma livunyelwe).
Kuzicelo ze-Software kanye namaseva
Amanye amadivaysi, ikakhulukazi amaseva enethiwekhi , anenethiwekhi engaphezulu kwesisodwa senethiwekhi. Izinhlelo zokusebenza ze-TCP / IP zisebenzisa i-0.0.0.0 njengendlela yokwenza uhlelo lokuhlola ithrekhi yenethiwekhi kuzo zonke amakheli we-IP okwamanje abelwe ukuxhumana phakathi kwale divayisi ehlukahlukene.
Ngenkathi ama-computer axhunyiwe awasebenzisi leli kheli, imilayezo ethwalwe nge-IP ngezinye izikhathi ihlanganisa 0.0.0.0 ngaphakathi kwekhanda leprotocol lapho umthombo womlayezo ungaziwa.
Okufanele Ukwenze Uma Ubona Ikheli le-IP 0.0.0.0
Uma ikhompiyutha ilungiselelwe kahle ukuxhumana kwe-TCP / IP okwamanje ikhombisa 0.0.0.0 yekheli, zama lokhu okulandelayo ukuxazulula le nkinga bese uthola ikheli elivumelekile:
- Kumanethiwekhi anezinsizakalo zokusekela ikheli, ukukhululwa nokuvuselela ikheli le-IP lekhompyutha. Ukungaphumeleli ngesabelo se-DHCP kungaba okuphakathi noma okuphikisanayo. Uma ukuhluleka kuqhubeka, cindezela ukucushwa kwesiphakeli se-DHCP: Izimbangela ezivamile zokuhluleka zihlanganisa ukungenawo amakheli atholakalayo echibini le-DHCP.
- Kumanethiwekhi adinga ukubhekana ne-IP ecacile, lungisa ikheli le-IP elivumelekile kukhompyutha
