Functions

func AddrRangeToPrefixes

func AddrRangeToPrefixes(start, end netip.Addr) []netip.Prefix

AddrRangeToPrefixes converts an ip address range into a list of CIDR prefixes.

func ParseIPNumber

func ParseIPNumber(rawIPNumber string) (addr netip.Addr, err error)

ParseIPNumber converts a raw base-10 IP number into an IP address. For example:

42540986356047386130018232263459733504 == 2001:1890:17dd:4500::

For numbers less than the max uint32 an IPv4 address is returned, else an IPv6 address is returned.

func PrefixToAddrRange

func PrefixToAddrRange(prefix netip.Prefix) (start, end netip.Addr)

PrefixToAddrRange returns a CIDR prefix's inclusive ip address range
