Oko kuthetha ntoni Xa Ubona i-0.0.0.0 Idilesi ye-IP
Iilwimi ze-IP kwi- Intanethi ye-Intanethi (IP) inguqulelo 4 (IPv4) ukusuka kwi-0.0.0.0 ukuya ku-255.255.255.255. Idilesi ye-IP 0.0.0.0 ineentsingiselo ezikhethekileyo kwiinkcukacha zekhompyutha. Nangona kunjalo, ayikwazi ukusetyenziswa njengedilesi yecandelo jikelele.
Idilesi ye-IP ihlelwe njengesiqhelo (iineendawo ezine zeenombolo) kodwa iyona yile dilesi yendawo yokuhlala okanye enye isetyenzisiweyo ukuchaza ukuba akukho idilesi evamile eyabelwe. Umzekelo, endaweni yokubeka idilesi ye-IP kwingingqi yenethiwekhi, i-0.0.0.0 ingasetyenziselwa ukuthetha nantoni na ukufumana zonke iidilesi ze-IP okanye ukuvimba zonke iidilesi ze-IP kumendo ongagqibekanga .
Kulula ukudibanisa i-0.0.0.0 kunye ne- 127.0.0.1 kodwa khumbula nje ukuba idilesi ezine ezine-zeros zisebenzisiweyo ezininzi (njengoko kuchaziwe ngezantsi) ngelixa i-127.0.0.1 inenjongo eyodwa ekhethekileyo yokuvumela ifowuni ukuba ithumele imiyalezo ngokwayo.
Qaphela: I-idilesi ye-0.0.0.0 ngezinye iindidi ibizwa ngedilesi ye-wildcard, idilesi engachazwanga okanye i- INADDR_ANY .
Yintoni i-0.0.0.0
Ngamafutshane, 0.0.0.0. idilesi engekho ehambayo echaza into engavumelekanga okanye engaziwayo. Nangona kunjalo, ithetha into eyahlukileyo kuxhomekeke ekubeni ingaba ibonwa kwisixhobo siklayenti njengekhomputha okanye kumatshini womncedisi.
Kwiikhompyutha zeKlayenti
Ii-PC nezinye izixhobo zamakhasimende ngokuqhelekileyo zibonisa idilesi ye-0.0.0.0 xa ingaxhunyiwe kwi-network TCP / IP . Ifowuni inokuzibeka yona le dilesi ngokungagqibekanga nanini na xa ingaxhunyiwe kwi-intanethi.
Kungenzeka kwakhona ngokunikezelwa ngokuzenzekelayo yi- DHCP kwimeko yokunqongophala kwesabelo sedilesi. Xa isetyenziswe kule dilesi, ifowuni ayikwazi ukuthetha kunye nayiphi na ifowuni kule ntanethi.
I-0.0.0.0 inokuthi isetyenziswe njenge- subnet mask mask kunokuba idilesi yayo ye-IP. Nangona kunjalo, i-subnet mask kunye nale xabiso ayinayo injongo. Bobabini idilesi ye-IP kunye nomnxeba wenethiwekhi ngokuqhelekileyo kubelwe 0.0.0.0 kumxhasi.
Ngokuxhomekeke kwendlela esetyenziswa ngayo, i-firewall okanye isofthiwe ye-router ingasebenzisa i-0.0.0.0 ukubonisa ukuba nganye idilesi ye-IP kufuneka ivalwe (okanye ivunyelwe).
Kwiisicelo zeeSoftware kunye nabaSeva
Amanye amacebo, ngokukodwa amaseva enethiwekhi , anesimo esibonakalayo somnatha omnye. Izicelo zesofthiwe ze-TCP / IP zisebenzisa i-0.0.0.0 njengendlela yokucwangcisa ubuchule ukubeka iliso kwi-intanethi kwi-idilesi ye-IP njengamanje eyabelwe kwi-interfaces kwi sixhobo ezininzi.
Ngexa iikhomputha ezixhunyiwe zingasebenzisi le dilesi, imilayezo ephathekayo nge-IP ngamanye amaxesha iquka i-0.0.0.0 ngaphakathi kwintloko yeprotocol xa umthombo womyalezo ungaziwa.
Oko Ukwenza Xa Ubona i-0.0.0.0 Idilesi ye-IP
Ukuba ikhompyutha iqulunqwe kakuhle kwi-network ye-TCP / IP okwangoku ibonisa 0.0.0.0 kwidilesi, zama oku okulandelayo ukujongana nale ngxaki uze ufumane idilesi efanelekileyo:
- Kwiisetyenziselwano ezineenkcukacha zenkxaso yesabelo, ukukhululwa nokuvuselela idilesi ye-IP yekhompyutha. Ukungaphumeleli ngesabelo se-DHCP sinokungena phakathi okanye kuqhubeke. Ukuba ukungaphumeleli kuqhubeka, uxhaphaza ukucwangciswa kweseva ye-DHCP: Izizathu eziqhelekileyo zokungaphumeleli kubandakanya ukungenazo idilesi ezikhoyo kwiziko leDHCP.
- Kwiinqanki ezifuna idilesi yokudibanisa i-IP, qwalasela idilesi ye-IP evumelekileyo kwikompyutha
