Qhov yuav tsum tau ua subnetting xws li peb tsim li ntau subnets raws li peb tuaj yeem nrog 30 tus tswv hauv txhua subnet . 2 -2, Qhov twg tus exponent n yog sib npaug rau tus naj npawb ntawm cov khoom tom qab subnet cov khoom qiv. peb suav tau ntau npaum li cas bits yuav tsum yog li ntawd txhua subnet muaj 30 tus tswv chaw nyob.
Ua li no, dab tsi yog tus naj npawb ntawm hosts ib subnet?
3 Teb. Cov tus lej siab tshaj ntawm muaj tus tswv yog 4094. Tau kawg, koj siv tsis tau tus IP thawj lossis zaum kawg hauv a subnet (e.g. 10.0. 0.0 thiab 10.0.
Tom qab ntawd, lo lus nug yog, pes tsawg tus tswv lub network muaj? Tag nrho tus naj npawb ntawm IPv4 tus tswv chaw nyob rau lub network yog 2 rau lub zog ntawm tus lej ntawm tus tswv tsev, uas yog 32 rho tawm tus lej ntawm cov khoom siv network. Rau peb qhov piv txwv ntawm /21 (network mask 255.255 . 248.0 network), muaj 11 host bits (32 chaw nyob me ntsis – 21 network khoom = 11 host bits).
Ib yam li ntawd, pes tsawg tus tswv nyob hauv 32 subnet?
IPv6 Subnet Tshuab xam zauv
