If we use a chain backend that only understands IP addresses (like Neutrino for example), we need to turn any Onion v2 host addresses into a fake IPv6 representation, otherwise it would be resolved incorrectly. To do this, we use the same fake IPv6 address format that bitcoind and btcd use internally to represent Onion v2 hidden service addresses.
