The external dynamic list can include individual IP addresses, subnet addresses (address/mask), or range of IP addresses. In addition, the block list can include comments and special characters such as
/. The syntax for each line in the list is
[IP address, IP/Mask, or IP start range-IP end range] [space] [comment].
Enter each IP address/range/subnet in a new line; URLs or domains are not supported in this list. A subnet or an IP address range, such as 220.127.116.11/24 or 192.168.20.40-192.168.20.50, count as one IP address entry and not as multiple IP addresses. If you add comments, the comment must be on the same line as the IP address/range/subnet. The space at the end of the IP address is the delimiter that separates a comment from the IP address.
