I propose a new feature: IPAddr#private?.
IPAddr.new("192.168.1.1").private? #=> true.
Import ipaddr 1.2.0
- Add IPAddr#prefix
- Add IPAddr#loopback?
- Add IPAddr#private? [Feature #11666]
- Add IPAddr#link_local? [Feature #10912]
- Reject invalid address mask [Bug #13399]
- Warn that IPAddr#ipv4_compat and #ipv4_compat? are deprecated [#Bug 13769]

- feature issues
- conflict with private visibility
- “private?” is different from visivility
- Behavior when address family is IPv6
- nil? false?
- or treat link-local, site-local (deprecated), unique-local as true?
- Naming differencies with Addrinfo
- The name “ipv4_private?” is clear that the method returns false on IPv6 addresses.

IPv6 has a private range too: d00::/8 (RFC 4193)
Also, there are more IP ranges that have been reserved for special use (there's an overview on https://en.wikipedia.org/wiki/Reserved_IP_addresses). I think it would be better to make 1 method that can return a pre-defined symbol of that range if the IP address is in that range. Otherwise, there would be an explosion in the number of IP addresses.

As far as I understand RFC4193 never defines its range being "private". There also are other private-ish address ranges e.g. fd00::/8. And what about v4-mapped v6 addresses? IPv6's situation is complicated (at least to me). I'd suggest OP to leave IPv6 situations untouched.
