-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello.
Isn't 198.18.0.0/15 a private range, like RFC 1918?
Its RFC 2544, which contains ranges reserved for internal benchmarking. The term here is "bogon". That is any address which should not be seen being routed on the public internet. This includes special-purpose addresses like CG-NAT and benchmarking addresses, as well as reserved addresses that have not been allocated.
Currently reserved IP ranges are not routed but may be revived later and have security consequences
In 2011, the IETF wrote RFC 6441 (BCP 171), in which they recommend that unallocated ranges should no longer be considered bogons due to the IPv4 exhaustion. Any range that are reserved for "eventual" public use should just be considered allocated. I don't believe Tor does any special filtering for bogons, only for certain local addresses in tor_addr_is_internal_(), specifically: fc00/7 fc80/10 fec0/10 ::/127 10/8 0/8 127/8 100.64/10 169.254/16 172.16/12 192.168/16 With special cases for binding to 0/32 and 100.64/10.
