Contoh 1: Untuk mengalokasikan alamat IP Elastis dari kolam alamat Amazon
Contoh
allocate-address
berikut mengalokasikan alamat IP Elastis. Amazon EC2 memilih alamat dari kumpulan alamat Amazon.aws ec2 allocate-address
Output:
{ "PublicIp": "70.224.234.241", "AllocationId": "eipalloc-01435ba59eEXAMPLE", "PublicIpv4Pool": "amazon", "NetworkBorderGroup": "us-west-2", "Domain": "vpc" }
Untuk informasi selengkapnya, lihat Alamat IP Elastis di Panduan EC2 Pengguna Amazon.
Contoh 2: Untuk mengalokasikan alamat IP Elastis dan mengaitkannya dengan grup batas jaringan
Contoh
allocate-address
berikut mengalokasikan alamat IP Elastis dan mengaitkannya dengan grup batas jaringan tertentu.aws ec2 allocate-address \ --network-border-group
us-west-2-lax-1
Output:
{ "PublicIp": "70.224.234.241", "AllocationId": "eipalloc-e03dd489ceEXAMPLE", "PublicIpv4Pool": "amazon", "NetworkBorderGroup": "us-west-2-lax-1", "Domain": "vpc" }
Untuk informasi selengkapnya, lihat Alamat IP Elastis di Panduan EC2 Pengguna Amazon.
Contoh 3: Untuk mengalokasikan alamat IP Elastis dari kolam alamat milik Anda
Contoh
allocate-address
berikut mengalokasikan alamat IP Elastis dari kolam alamat yang Anda bawa ke akun Amazon Web Services. Amazon EC2 memilih alamat dari kumpulan alamat.aws ec2 allocate-address \ --public-ipv4-pool
ipv4pool-ec2-1234567890abcdef0
Output:
{ "AllocationId": "eipalloc-02463d08ceEXAMPLE", "NetworkBorderGroup": "us-west-2", "CustomerOwnedIp": "18.218.95.81", "CustomerOwnedIpv4Pool": "ipv4pool-ec2-1234567890abcdef0", "Domain": "vpc" "NetworkBorderGroup": "us-west-2", }
