Creating IP Address Block Exclusions lists

You can unblock an IP address that has been added to the Block List one of two ways:

• Remove the IP address from the Block List
• Override the block by adding the IP address to the Block Exclusions List

When to add an IP address to a Block Exclusions list

All IP addresses are unblocked by default and are only blocked when added to the Block List. Adding an address to the Unblock List is useful when an IP address is on the Block List but you don't want it blocked, for example, when you have put a range of addresses in the Block List and you want a single address in the range to be unblocked.
