Functions ¶

func Add ¶

func Add(addr netip.Addr, offset *big.Int) (result netip.Addr, ok bool)

Add adds a non-negative offset to an address. ok is false on invalid input or family overflow.

func Distance ¶

func Distance(start, end netip.Addr) (distance *big.Int, ok bool)

Distance returns end-start. ok is false for mixed families or end before start.

func ParseAddr ¶

func ParseAddr(s string) (netip.Addr, error)

ParseAddr parses an IPv4 or IPv6 address. IPv4-mapped IPv6 representations are rejected so callers cannot accidentally change address families through netip.Addr.Unmap.

func PrefixAddressCount ¶

func PrefixAddressCount(addressBits, prefixLen int) *big.Int

PrefixAddressCount returns the number of IP addresses in a prefix.

Types ¶

type IPRange ¶

type IPRange struct {
	Start netip.Addr
	End   netip.Addr
}

IPRange is the internal representation of a contiguous IPv4 or IPv6 address range. Start and End must always belong to the same address family.

func ExcludeRanges ¶

func ExcludeRanges(parent IPRange, allocated []IPRange) []IPRange

ExcludeRanges returns all sub-ranges of parent that are not covered by any range in allocated.

func MergeRanges ¶

func MergeRanges(ranges []IPRange) []IPRange

MergeRanges merges overlapping/adjacent IP ranges into a minimal set. Mixed families remain separate.

func RangeFromPrefix ¶

func RangeFromPrefix(prefix netip.Prefix) (IPRange, error)

RangeFromPrefix returns the inclusive address range covered by prefix.

func SortRanges ¶

func SortRanges(ranges []IPRange) []IPRange

SortRanges returns a copy of the ranges sorted by family, start address, then end address.

func SubtractRange ¶

func SubtractRange(ranges []IPRange, sub IPRange) []IPRange

SubtractRange returns ranges with sub removed, splitting any overlapping range around it.

func (IPRange) In ¶

func (r IPRange) In(other IPRange) bool

In reports whether r is fully contained within other.

func (IPRange) InAny ¶

func (r IPRange) InAny(ranges []IPRange) bool

InAny reports whether r is fully contained within any of the given ranges.

func (IPRange) Overlaps ¶

func (r IPRange) Overlaps(other IPRange) bool

Overlaps reports whether r shares at least one IP with other.
