Tsis tas li ntawd, muaj pes tsawg subnets nyob hauv VPC? 0.0/16. Default subnets nyob rau hauv lub neej ntawd VPC tau muab / 20 netblocks nyob rau hauv lub VPC CIDR ntau.
Raws li txoj cai, VPC hauv AWS yog dab tsi thiab nws ua haujlwm li cas?
Amazon Virtual Private Huab (Amazon VPC ) tso cai rau koj muab ib qho kev sib cais ntawm lub logic AWS Huab qhov twg koj tuaj yeem tso tawm AWS cov peev txheej hauv lub network virtual uas koj txhais. Koj tuaj yeem siv IPv4 thiab IPv6 hauv koj li VPC kom ruaj ntseg thiab yooj yim nkag mus rau cov peev txheej thiab cov ntawv thov.
VPC ua AWS li cas?
Amazon Virtual Private Huab (Amazon VPC ) enables koj mus tso tawm AWS cov peev txheej rau hauv lub network virtual uas koj tau txhais. Lub network virtual no zoo ib yam li lub network ib txwm siv uas koj yuav ua haujlwm hauv koj tus kheej cov ntaub ntawv chaw, nrog rau cov txiaj ntsig ntawm kev siv cov txheej txheem scalable ntawm AWS.

Dab tsi ua raws li kev ruaj ntseg ntxiv ntawm qib subnet hauv VPC?
Lub Network ACLs (NACLs) yog ib txheej txheej txheej ntawm kev ruaj ntseg rau VPC uas ua raws li lub foob pob hluav taws rau kev tswj cov tsheb khiav hauv thiab tawm ntawm ib lossis ntau lub subnets. Default ACL tso cai rau tag nrho cov tsheb khiav hauv thiab sab nraud
Dab tsi yog qhov chaw nyob IP thawj zaug thiab zaum kawg hauv subnet 1?
Feem ntau, thawj qhov chaw nyob yog kev txheeb xyuas lub network thiab qhov kawg yog qhov tshaj tawm, lawv tsis tuaj yeem siv raws li qhov chaw nyob. Nco ntsoov tias koj tsis tuaj yeem siv qhov chaw nyob thawj thiab zaum kawg hauv qhov ntau yog tias nws yog siv los suav cov khoom siv hauv kev tshaj tawm xov xwm (xws li lub cev lub cev lossis vlan thiab lwm yam)
255.255 254.0 subnet yog dab tsi?
255.255.254.0 = 23 bits mask = 510 hosts (512 -2) 255.255.252.0 = 22 bits mask = 1022 hosts (1024 -2) 255.255.248.0 = 21 bits party multiply = 204 bits hosts los yog faib los ntawm 2..thiab tshem tawm 2 tus tswv (tshaj tawm thiab network)
Ua li cas koj subnet subnet?
Tag nrho cov subnets: Siv lub npog ntsej muag subnet 255.255. 255.248, tus lej tus nqi 248 (11111000) qhia tias 5 cov khoom siv los txheeb xyuas cov subnet. Txhawm rau nrhiav tag nrho cov subnets muaj tsuas yog nce 2 mus rau lub zog ntawm 5 (2^5) thiab koj yuav pom tias qhov tshwm sim yog 32 subnets
Dab tsi yog IP chaw nyob hauv subnet?
