First reminder, that there are:
- Static Public IPs. These don't change.
- Dynamic Public IPs. Are changed if the resource attached to IP is deallocated.
Public IP pricing is as follows:
1. Dynamic IP costs ~ 3$ /month
2. Static IP costs the same as Dynamic IP + a reservation cost, which also is ~ 3$/month
3. Also, first 5 Public IPs don't have reservation cost.
