Need help with IPv6 block range

    I am getting external hits from Facebook, they are coming from IP’s like this…
    2a03:2880:23ff:d::face:b00c

    Note the last characters. I do not know how to set up a range that blocks all these, tried this with different end characters, but WF does not see it as a valid range…
    ****:****:****:*::face:b00c

    Thank you for any help.

    Hi @seedy

    That IP is in this CIDR range:

    2A03:2880:2300::/40

    The first and last IP addresses are:

    2A03:2880:2300:0000:0000:0000:0000:0000
    2A03:2880:23FF:FFFF:FFFF:FFFF:FFFF:FFFF

    Checking both IP’s shows that the whole range appears to be owned by Facebook so you can block the CIDR range 2A03:2880:2300::/40

    You can’t use wildcards for IP addresses and why your rule doesn’t work.
