# IP Methods

###### tags: `Networking`

Stabilization PR: https://github.com/rust-lang/rust/pull/76098

This document lists the methods tracked under the `ip` feature, whether they're covered by an EITF RFC, and whether the behavior matches corresponding methods in other languages.

Emoji Key:

| ✅ | ❓ | 🔎 | ❌ |
| ---------------- | --- | ---------------------------------------------------- | ----------------- |
| Behavior matches | Method does not exist | Source code is not provided | Behavior mismatch |

Anything other than "❓" is a link that will take you to the documentation / source code for that language's equivalent.

Unless otherwise noted, Rust behavior matches that of the RFC Spec provided.
