Yog tias koj muaj lub network loj, tej zaum koj xav tsim cov tes hauj lwm me me. Qhov no vim tias koj tuaj yeem tswj hwm lawv tau yooj yim dua. Cov tes hauj lwm me me kuj muaj kev nyab xeeb dua thiab zoo li txo kev sib tsoo. Nws tuaj yeem yog txoj haujlwm nyuaj thiab nyuaj rau subnet Class C network. Txawm li cas los xij, nws yog qhov txuj ci tseem ceeb kom paub. Subnet Class C network los ntawm kev ua cov hauv qab no.
Cov kauj ruam
Kauj Ruam 1. Txheeb tus IP chaw nyob thiab tus tswv lub subnet daim npog qhov ncauj
Thaum koj txheeb xyuas cov no, koj yuav muaj peev xwm tau txais cov ntaub ntawv hauv qab no:
- Qhov chaw ntawm tus tswv tsev subnet.
- Subnet qhov chaw tshaj tawm.
- Subnet siv tau tus tswv tsev ntau yam uas tau siv los teeb tsa tus tswv tsev.
Kauj Ruam 2. Nrhiav seb qhov chaw nyob tshaj tawm yog dab tsi
Tom qab koj tau txais lub subnet, nws yog ib qho tseem ceeb kom nkag siab tias qhov chaw tshaj tawm hauv xov tooj cua tsis yog qhov chaw nyob raug cai. Yog li, koj tsis tuaj yeem muab nws rau tus tswv tsev teeb tsa. Thaum koj kawm paub dab tsi subnet thiab chaw nyob tshaj tawm, nws yuav yooj yim dua rau koj kom paub tus tswv chaw nyob. Qhov ntawd yog vim tias tus tswv tsev muaj ntau tus lej ntawm qhov chaw nyob tshaj tawm thiab chaw nyob subnet.
Kauj Ruam 3. Tau txais qhov ntau ntawm subnets
Nrhiav paub tus naj npawb ntawm subnets los ntawm kev siv cov qauv hauv qab no: 2ⁿ. Cov n tivthaiv yog tus naj npawb ntawm subnet cov khoom hauv daim npog. Me ntsis yog qhov tsawg tshaj plaws ntawm cov ntaub ntawv hauv computer. Nws muaj tus lej binary nkaus xwb, uas yog 0 lossis 1. Hauv computer lub ntsiab lus, 0 txhais tau tias tawm thaum 1 txhais tau tias. Rau subnets, ntsis yog 1, uas kuj txhais tau tias nws nyob ntawm.
Kauj Ruam 4. Tau txais tus naj npawb ntawm cov tswv
Tshawb nrhiav seb tus tswv tsev siv tus lej li cas hauv qab no: 2ⁿ - 2. Cov n tivthaiv yog tus naj npawb ntawm cov tswv cuab hauv daim npog ntsej muag. Rau tus tswv tsev, qhov me me yog 0, uas txhais tau tias nws tawm.
Kauj Ruam 5. Ntsuas lub npog ntsej muag uas koj xav tau rau lub network
Koj yuav tsum nrhiav tus naj npawb ntawm sub-tes hauj lwm nrog rau tus tswv rau txhua lub network. Tom qab koj tau txais cov ntaub ntawv no, koj yuav tsum tau siv tib lub mis, uas yog 2ⁿ - 2.
Kauj Ruam 6. Xa mus rau Class C daim npog ntsej muag los tsim cov subnetworks
Txoj hauv kev zoo tshaj plaws los tsim sub-tes hauj lwm yog kom cim tau Class C qhov ncauj qhov ntswg. Lub default subnet mask yog 255.255.255.0. Muaj lwm lub subnet qhov ncauj qhov ntswg uas ua rau Chav C.
Kauj Ruam 7. Txiav txim siab daim npog C Class twg uas yuav siv rau koj cov sub-tes hauj lwm
Ua cov kauj ruam no tom qab koj tau txiav txim siab koj cov tes hauj lwm thiab cov tswv. Piv txwv li, yog tias koj xav tsim yim yim-tes hauj lwm sib txuas. Txhua tus ntawm lawv xav tau kaum tus tswv. Daim npog C Class koj yuav siv yog 255.255.255.240. Qhov no yog vim tias binary rau 240 yog 11110000. Nco ntsoov, subnet ntsis yog 1, thaum tus tswv me ntsis yog 0. Yog li ntawd, hauv 240, muaj plaub qhov khoom rau subnet thiab plaub khoom rau tus tswv. Siv cov qauv, 2ⁿ - 2, koj yuav tau txais 14 subnets thiab 14 tus tswv.
