go-multiaddr is a Go implementation of the multiaddr specification for representing network addresses. It provides a library for parsing, manipulating, and converting multiaddr strings and byte representations, with support for encapsulating/decapsulating addresses, protocol inspection, and conversion to/from standard net.Addr types. The repository includes a CLI utility for debugging multiaddrs, network address conversion utilities (manet), IP filtering capabilities, and a specialized pattern matching engine (meg) for multiaddr components. The architecture centers around immutable Multiaddr ([]Component) and Component types, with extensibility via protocol definitions and transcoders.
