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
. The syntax for each line in the list
[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 18.104.22.168/24 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.
An example IP address list:
2001:db8:123:1::1 #test IPv6 address
192.168.20.0/24 ; test internal subnet
2001:db8:123:1::/64 test internal IPv6 range
For an IP address that is blocked, you can display a notification
page only if the protocol is HTTP.
