domain.Check()

This package contains a single function that checks the validity of a domain name.

A domain name must respect rules defined in

• section 3.5 of RFC 1034 ("Domain names - concepts and facilities")
• section 2 of RFC 1123 ("Requirements for Internet Hosts -- Application and Support")

The domain.Check function ensures that the domain name respect those rules. If not, it returns an error explaining the detected problem.

Prerequisites

The package has no prerequisites and external dependencies.

Installation

To install or update this package use the instruction:

go get -u "github.com/chmike/domain"

Usage examples

The Check function can be used to check the validity of host or domain names.

name := "host.example.com"
if err := domain.Check(name); if err != nil {
    log.Fatalf("invalid domain name '%s': %v", name, err)
}
