Functions

func ValidateAddr

func ValidateAddr(s string) bool

ValidateAddr will parse a netip.AddrPort from string, and return the result of ValidateIP() on addr.

func ValidateIP

func ValidateIP(ip netip.Addr) bool

ValidateIP returns whether IP is an IPv4/6 address in non-reserved, public ranges.
