ip_addr feature

[tailhook]

Well, the feature is removed rust-lang/rust#27801

You mentioned in #1 that feature is "too deep in the code", but now it's gone. Any plans to remove it? Will you use ip crate from @dimbleby?

There's some discussion on rust-lang/rust#27705 about bringing IpAddr back. Once that issue is decided, if IpAddr remains deprecated, I'll change things over to use the ip crate.

Understood.
