IPIsGlobal returns true if the given IP is a global address.

func IPIsLAN

func IPIsLAN(ip net.IP) bool

IPIsLAN returns true if the given IP is a site-local or link-local address.

func IPIsLinkLocal

func IPIsLinkLocal(ip net.IP) bool

IPIsLinkLocal returns true if the given IP is a link-local address.

func IPIsLocalhost

func IPIsLocalhost(ip net.IP) bool

IPIsLocalhost returns whether the IP refers to the host itself.

func IPIsSiteLocal

func IPIsSiteLocal(ip net.IP) bool

IPIsSiteLocal returns true if the given IP is a site-local address.

func IsValidFqdn

func IsValidFqdn(fqdn string) bool

IsValidFqdn returns whether the given string is a valid fqdn.
