AddIPOffset adds the provided integer offset to a base big.Int representing a net.IP NOTE: If you started with a v4 address and overflow it, you get a v6 result.

BigForIP creates a big.Int based on the provided net.IP.

GetIndexedIP returns a net.IP that is subnet.IP + index in the contiguous IP space.

IsDualStackCIDRs returns if - all are valid cidrs - at least one cidr from each family (v4 or v6).

IsDualStackCIDRStrings returns if - all are valid cidrs - at least one cidr from each family (v4 or v6).

IsDualStackIPs returns if a slice of ips is: - all are valid ips - at least one ip from each family (v4 or v6).

IsDualStackIPStrings returns if - all are valid ips - at least one ip from each family (v4 or v6).

IsIPv6 returns if netIP is IPv6.

IsIPv6CIDR returns if a cidr is ipv6.

IsIPv6CIDRString returns if cidr is IPv6.

IsIPv6String returns if ip is IPv6.

NewLocalPort returns a LocalPort instance and ensures IPFamily and IP are consistent and that the given protocol is valid.

ParseCIDRs parses a list of cidrs and return error if any is invalid.

ParseIPNets parses string slice to IPNetSet.

ParseIPSet parses string slice to IPSet.

ParsePort parses a string representing an IP port.

RangeSize returns the size of a range in valid addresses.

ListenPortOpener opens ports by calling bind() and listen().

LocalPort represents an IP address and port pair along with a protocol and potentially a specific IP family.

Closeable closes an opened LocalPort.

PortOpener can open a LocalPort and allows later closing it.

IPFamily refers to a specific family if not empty, i.e.

IPNetSet maps string to net.IPNet.

IPSet maps string to net.IP.

Protocol is a network protocol support by LocalPort.
