Hi, I'm using Tor in transparent mode, and I'm running into a rather inconvenient behavior. VirtualAddrNetworkIPv6 refuses to parse unless the network address given is a /40 or broader. However, IPv6 ULA, which makes it very easy to give Tor its own subnet no-strings-attached, strictly grants a /48 prefix. As a result, I am faced with a choice between deeply suboptimal options: 1.) Use VirtualAddrNetworkIPv4, as I've done in the past. This results in _fewer_ addresses being available to Tor than an IPv6 /48, which I feel illustrates the issues with requiring a /40 quite clearly. 2.) Squat on some portion of the IPv6 address space I don't actually own. This is entirely unpalatable
