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?

7

    I think you may be missing a double colon somewhere.

  • No that's not it, whatismyipaddress.com reports my address without any double colons and .htaccess successfully blocks my IP address with the seven groups.

  • @kasperd I'm not sure how that helps but if you are referring to not releasing personal information then, thanks, but I had said "My IPv6 address is like this (some digits changed)".

As described for example on wikipedia, you can shorten these addresses and omit zeros if it is unambiguous.

For example:

The loopback address, 0000:0000:0000:0000:0000:0000:0000:0001, may be abbreviated to ::1 by using both rules.

So give it a try once more to have a look at your real IP if you don't miss some colon : or something else.
