IP Addresses
  • When you start and stop an instance with a public IPv4 address, its public IPv4 address changes.
    • However, this can be solved with Elastic IP addresses.

Elastic IP addresses

  • It is is a static IPv4 address designed for dynamic cloud computing.
  • You can mask the failure of an instance or software by rapidly remapping the address to another instance in your account.
  • An Elastic IP address is allocated to your AWS account, and is yours until you release it.
  • A public IPv4 address (reachable from the internet).
