There is 1 good thing about EIP and 1 bad thing. The good thing is EIP is free to use. You don't need to pay anything for the static IP you are using. How cool! The bad thing is, when EIP is not attached to an instance, it cost you money. In today's post we are going to do a hands-on on how to kill a dangling EIP or in other words, deallocate an unassigned Elastic IP.
