Functions

func AddrAsIP

func AddrAsIP(addr netip.Addr) net.IP

AddrAsIp converts a netip.Addr to a net.IP.

func HasPort

func HasPort(addr string) bool

HostPort returns whether addr includes a port number (i.e., is of the form HOST:PORT).

func IPAsAddr

func IPAsAddr(ip net.IP) netip.Addr

IPAsAddr converts a net.IP to a netip.Addr.

func IsIPv4

func IsIPv4(s string) bool

IsIPv4 returns true iff the addr string represents an IPv4 address.

func IsIPv6

func IsIPv6(s string) bool

IsIPv6 returns true iff the addr string represents an IPv6 address.

func TryAddPort

func TryAddPort(server string, port string) string

TryAddPort checks whether the server string already has a port (i.e., ends with ':<PORT>'. If it does, thn the function simply returns that string. If it does not, it returns the server string with the port appended.
