s has the advantage of absolutely
        guaranteeing the new address is within the network space (whereas the
        method employed below could *theoretically* generate an overlapping
        address), but would in turn remove any ability to compress obfuscated
        addresses to match the general format/syntax of the address it is
        replacing. For the moment, it is assumed that being able to maintain a
        quick mental note of "unobfuscated device ff00::1 is obfuscated device
        53ad::a1b2" is more desireable than "ff00::1 is now obfuscated as
        53ad::1234:abcd:9876:a1b2:".

        :param addr:        The unobfuscated IPv6 address
        :type addr:         ``ipaddress.IPv6Address``

        :returns:           An obfuscated address within this network
        :rtype:             ``str``
