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.

Functions ¶
func DomainFromFqdn ¶
DomainFromFqdn returns domain name or empty string
func HostFromURL ¶
HostFromURL extraxts hostname from given URL
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
func IsIPv6 ¶
IsIPv6 (ipaddr) return true if string ip contains a valid representation of an IPv6 address
func IsNetwork ¶
IsNetwork (network) return true if string network contains a valid representation of an ip network
func NormaliseDomainToPunycode ¶
NormaliseDomainToPunycode returns normalised domain name as Punycode
func NormaliseDomainToUnicode ¶
NormaliseDomainToUnicode returns normalised domain name as Unicode
func NormaliseFQDNToPunycode ¶
NormaliseFQDNToPunycode returns normalised domain name as Punycode
func NormaliseFQDNToUnicode ¶
NormaliseFQDNToUnicode returns normalised domain name as Unicode
func NormaliseIPAddr ¶
NormaliseIPAddr return ip adresse without /32 (IPv4 or /128 (IPv6)
func NormaliseURLToPunycode ¶
NormaliseURLToPunycode returns normalised URL string.
func NormaliseURLToUnicode ¶
NormaliseURLToUnicode returns normalised URL string.
func ReverseIPAddr ¶
ReverseIPAddr (ipaddr) reverses string ip (use e.g. for DNS blacklists)
