AWS – サブネット情報の取得
概要
サブネットの情報を取得する方法について記載しています。
サブネット
VPC を作成するときに、その VPC に対して、IPv4 アドレスの範囲を Classless Inter-Domain Routing (CIDR) ブロックの形式で指定する必要があります (例: 10.0.0.0/16)。
手順
サブネットの情報を取得するには次のコマンドを実行します。
aws ec2 describe-subnetsTEXT
SUBNETS False ap-northeast-1a 250 10.0.0.0/24 False True available subnet-04c4084* vpc-8db025e*
TAGS Name sub-ext-a-project-01
SUBNETS False ap-northeast-1c 251 10.0.1.0/24 False False available subnet-da2db88* vpc-8db025e*
TAGS Name sub-ext-c-project-01
SUBNETS False ap-northeast-1a 251 10.0.2.0/24 False False available subnet-0fa5fd4* vpc-8db025e*
TAGS Name sub-int-a-project-01
SUBNETS False ap-northeast-1c 251 10.0.3.0/24 False False available subnet-112cb94* vpc-8db025e*
TAGS Name sub-int-c-project-01
