A client uses the website 'whatsmyip' website to determine their IP address. What they return is something like 2001:8003:52ed:4700:d9f:ac11:4f79:xxxx
Do the same rules apply in creating blocks in the htaccess file?
For example, can I add: allow from 2001:8003 to permit access to all IP's starting with 2001:8003?
