Elastic IP (EIP) Cheat Sheet

Official Link

  • An EIP is a public IPv4 address reachable from the Internet owned by Amazon and reserved for the user who allocates it until it is released by the user
  • It is possible to recover a released EIP if it was not allocated by another user
  • Users get charged only by idling (not-using) EIPs, i.e. not associate them with running instances
  • Soft limit of 5 EIPs per account per region
