Paub yuav suav li cas network thiab tshaj tawm chaw nyob yog tias koj muaj IP chaw nyob thiab subnet daim npog yog qhov tseem ceeb los teeb tsa lub network. Qhov wikiHow no qhia koj yuav xam koj li Network chaw nyob thiab Chaw nyob Tshaj tawm.

Cov kauj ruam

Txoj Kev 1 ntawm 3: Siv Classful Network

Kauj Ruam 1. Txiav txim siab tag nrho cov khoom siv rau subnetting

Rau kev sib koom ua ke hauv network tag nrho cov khoom yog 8. Thiaj li cov khoom sib xws = T_b = 8. Tag nrho cov khoom siv rau subnetting (n) tau txiav txim siab los ntawm subnet daim npog qhov ncauj.

Subnet qhov ncauj qhov ntswg tuaj yeem yog 0, 128, 192, 224, 240, 248, 252, 254 thiab 255.
Tus naj npawb ntawm cov khoom siv rau subnetting (n) rau lawv qhov sib thooj subnet yog raws li hauv qab no: 0 = 0, 128 = 1, 192 = 2, 224 = 3, 240 = 4, 248 = 5, 252 = 6, 254 = 7 thiab 255 = 8.
Subnet daim npog 255 yog lub neej ntawd, yog li nws yuav tsis raug txiav txim siab rau subnet masking.
Piv txwv: Cia peb xav tias tus IP chaw nyob yog 210.1.1.100 thiab Subnet daim npog yog 255.255.255.224. Tag nrho cov khoom = T._b = 8. Tus naj npawb ntawm cov khoom siv rau subnetting rau subnet daim npog 224 yog 3.

Kauj Ruam 2. Txiav txim siab tus naj npawb ntawm cov khoom sab laug rau tus tswv tsev

Qhov sib npaug los txiav txim siab tus naj npawb ntawm cov khoom sab laug rau tus tswv yog (m) = T_b -n. Los ntawm cov kauj ruam dhau los, koj tau txais tus lej ntawm cov khoom siv rau subnetting (n) thiab koj paub tag nrho cov khoom siv "T_b= 8 ". Tom qab ntawd koj tuaj yeem tau txais tus lej ntawm cov khoom seem rau tus tswv los ntawm kev rho tawm 8-n.

Siv cov piv txwv saum toj no, n = 3. Tus naj npawb ntawm cov khoom tshuav rau tus tswv yog (m) = 8 - 3 = 5. 5 yog tus lej ntawm cov khoom koj tau tawm mus ua tswv

Kauj Ruam 3. Xam tus naj npawb ntawm subnets

Tus naj npawb ntawm subnets yog 2^{. Tus naj npawb ntawm tus tswv ib subnet = 2^m - 2.}

Hauv peb qhov piv txwv, tus naj npawb ntawm subnets yog 2^{= 2³ = 8. 8 yog tus naj npawb ntawm subnets.}

Kauj Ruam 4. Xam tus nqi ntawm qhov kawg siv rau subnet masking

Tus nqi ntawm qhov kawg siv rau subnet masking yog (Δ) = 2^m.

Hauv peb qhov piv txwv, tus nqi ntawm qhov kawg siv rau subnet masking yog Δ = 2⁵ = 32. Tus nqi ntawm qhov siv me ntsis kawg yog 32.
