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 * , : , ; , #, or /. 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 92.168.20.0/24 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:

192.168.20.10/32 
	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 
	192.168.20.40-192.168.20.50
