Functions

func HostnameIsValid

func HostnameIsValid(hostname string) bool

HostnameIsValid provides a way for servers to check whether a looked-up client hostname is valid (see InspIRCd #1033 for why this is required).

This function shouldn't be called by clients since they don't need to validate hostnames for IRC use, just by servers that need to confirm hostnames of incoming clients.

In addition to this function, servers should impose their own limits on max hostname length -- this function limits it to 200 but most servers will probably want to make it smaller than that.

Types

type UserHost

type UserHost struct {
	Nick string
	User string
	Host string
}

UserHost holds a username+host combination

func ParseUserhost

func ParseUserhost(userhost string) UserHost

ParseUserhost takes a userhost string and returns a UserHost instance.
