Functions

func HostID

func HostID(addr netip.Addr, bits uint) uint64

HostID masks out the 'bits' most-significant bits of addr. The result is undefined if bits > addr.BitLen().

func SubnetRange

func SubnetRange(network, subnet netip.Prefix) (start, end uint64)

SubnetRange returns the amount to add to network.Addr() in order to yield the first and last addresses in subnet, respectively.

func ToIPNet

func ToIPNet(p netip.Prefix) *net.IPNet

ToIPNet converts p into a *net.IPNet, returning nil if p is not valid.

func ToPrefix

func ToPrefix(n *net.IPNet) (netip.Prefix, bool)

ToPrefix converts n into a netip.Prefix. If n is not a valid IPv4 or IPV6 address, ToPrefix returns netip.Prefix{}, false.
