Functions ¶

func AddrPortFromNet ¶

func AddrPortFromNet(addr net.Addr) netip.AddrPort

AddrPortFromNet converts a net.Addr into a netip.AddrPort.

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 LastAddr ¶

func LastAddr(p netip.Prefix) netip.Addr

LastAddr returns the last address of prefix 'p'.

func PrefixAfter ¶

func PrefixAfter(prev netip.Prefix, sz int) netip.Prefix

PrefixAfter returns the prefix of size 'sz' right after 'prev'.

func PrefixCompare ¶

func PrefixCompare(a, b netip.Prefix) int

PrefixCompare two prefixes and return a negative, 0, or a positive integer as required by slices.SortFunc. When two prefixes with the same address is provided, the shortest one will be sorted first.

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.
