iprange

This package helps you to work with IP ranges.

IP range is a set of IP addresses. Both IPv4 and IPv6 are supported.

IP range interface:

type Range interface {
    Family() Family
    Contains(ip net.IP) bool
    Size() *big.Int
    fmt.Stringer
}

Supported formats

• IPv4 address (192.0.2.1)
• IPv4 range (192.0.2.0-192.0.2.10)
• IPv4 CIDR (192.0.2.0/24)
• IPv4 subnet mask (192.0.2.0/255.255.255.0)
• IPv6 address (2001:db8::1)
• IPv6 range (2001:db8::-2001:db8::10)
• IPv6 CIDR (2001:db8::/64)

IP range doesn't contain network and broadcast IP addresses if the format is IPv4 CIDR, IPv4 subnet mask or IPv6 CIDR.
