Constants

const DomainRegexpStr = "^([a-z0-9]+(-[a-z0-9]+)*\\.)+[a-z]{2,}$"

DomainRegexpStr is a regular expression string to validate domains.

Variables

var ExtendedTLDs = map[string]bool{
	"BIT":   true,
	"ONION": true,
}

ExtendedTLDs is a set of additional "TLDs", allowing decentralized name systems, like TOR and Namecoin.

var TLDs = map[string]bool{}/* 725 elements not displayed */

TLDs is a set of TLDs, according to ICANN in 2014.

Functions

func IsDomain

func IsDomain(s string) bool

IsDomain returns whether given string is a domain. It first checks the TLD, and then uses a regular expression.

func IsExtendedTLD

func IsExtendedTLD(s string) bool

IsExtendedTLD returns whether the given string is a TLD (Top Level Domain), extended with a few other "TLDs": .bit, .onion

func IsICANNTLD

func IsICANNTLD(s string) bool

IsICANNTLD returns whether the given string is a TLD (Top Level Domain), according to ICANN. Well, really according to the TLDs listed in this package.

func IsTLD

func IsTLD(s string) bool

IsTLD returns whether the given string is a TLD (according to ICANN, or in the set of ExtendedTLDs listed in this package.
