Introduction
This library contains some basic validation and helpers for handling ip addresses (IPv4 + IPv6), ip ranges (from - to ip adress, IPv4 + IPv6), domain names, fqdn (fully qualified domain names), and urls.
Please see the unit tests (xx_test.go) for examples.

func IntToIP ¶
IntToIP (int) return net.IP from the integer representation of an ip address (use e.g. for IP2Location databases )
func IsDomain ¶
IsDomain (domainname string) returns true is domainname is a valid domain, otherwise false
func IsFQDN ¶
IsFQDN (fqdn) returns true if fqdn is a FQDN (Fully Qualified Domain Name) hostname + domainname + tld, otherwise false
func IsIPAddr ¶
IsIPAddr return true if string ip contains a valid representation of an IPv4 or IPv6 address
func IsIPRange ¶
IsIPRange (range) return true if string r contains a valid representation of an ip network (e.g. 192.168.10.1-192.168.10.199)
func IsIPv4 ¶
IsIPv4 (ipaddr) return true if string ip contains a valid representation of an IPv4 address
