Please use `net-literals` instead:
Macros for writing literal IP addresses.
See https://github.com/rust-lang/rfcs/issues/1926 for the background behind this crate.
This crate uses the recently implemented procedural macros feature, and so requires a nightly version of the compiler.
If you use rustup (recommended), then you can install Rust nightly using these instructions.
