My IPv6 address is like this (some digits changed):
2001:569:78f0:ca00:bcaa:d016:4
...as reported by whatismyipaddress.com.
This is strange because I understand that there should be eight blocks not seven. I added this to the .htaccess file of my website and it successfully blocks me from accessing the site:
order allow,deny
deny from 2001:569:78f0:ca00:bcaa:d016:4
allow from all
Question: What is the full eight block equivalent of my IPv6 address?
