Mafunso ofunsidwa nthawi zambiri
Kodi mabungwe ambiri ndi m’malo subnet?
A / n subnet ali 2 ^ (32 - n) adiresi, minus awiri anatenga kwa netiweki ndi broadcast. A / 24 ali 256 adiresi ndi 254 ntchito mahosts.
Kodi ndi chiyani wildcard mask?
Wildcard mask ndi bit-by-bit reverse ya subnet mask (255.0 → 0.255).Access-kuwongolera mnda ndi OSPF kugwiritsa ntchito izo kuti agwirizane ndi mnda wa adiresi.
Kodi pali kusiyana kotani pakati pa netiweki ndi adiresi yofalitsa?
Adiresi ya netiweki (zomwe zonse ndi ma bit 0) imapatsa dzina la subnet; adiresi yofalitsa (zomwe zonse ndi ma bit 1) imafika pazomwe zonse zilipo. Palibe chomwe chimaperekedwa kwa chipangizo.
Kodi CIDR prefix (/24, /16) kumatanthauza chiyani?
Ndi idadi ya ma bit oyamba omwe amapanga gawo la netiweki la adiresi. A prefix wamkulu amatanthauza ma bit ambiri a netiweki ndi ma bit ochepa a ma host, kotero subnet wamkulu: /24 amapatsa ma hosts 254, /25 amapatsa 126, ndipo kamodzi ka bit kambiri kumadula gawo.
Kodi ndingatani kuti ndichepetse netiweki m'ma subnets ang'onoang'ono?
Kutenga ndalama za ma hosts ndi kuwonjezera ma prefix. Kugawa /24 kukhala awiri /25s kumapatsa ma blocks awiri a 126 ma hosts; kupita ku /26 kumapatsa ma blocks awiri a 62. Kawirikawiri, ma prefix bit amawonjezera kuchuluka kwa subnets ndi kuchepetsa kukula kwawo.
Kodi ndi IP adiresi gulu?
M'zaka za zana la 19, makompyuta ayamba kulandira ma adilesi a IP kuchokera ku makompyuta ena, ndipo tsopano ma adilesi a IP amagawidwa m'magulu atatu: A (1-126), B (128-191) ndi C (192-223) kwa ma unicast, D kwa ma multicast ndi E otetezeka.
Kodi ndi / 31 ndi / 32 subnets ntchito?
A / 31 ali ndi ma adilesi awiri okha ndi palibe kufalitsa, kugwiritsira ntchito kwa point-to-point kugwirizana pakati pa ma routers. A / 32 ndi imodzi ma adilesi woyang'anira, wofala kwa loopbacks ndi ma host njira.
API — kugwiritsa ntchito izi calculator kuchokera code
