Some addresses can have hundreds of thousands of potential string Produce all common address strings of different formats for a given IPv4 or IPv6 address and produce collections of such strings Whether IPv4/6, or subnets, or inet_aton formats, and so on. The way that Java’s InetAddress.getByName does)Īllow control over which formats are allowed when parsing, Only, it will not be treated as a host with DNS lookup attempted in (for instance, when validating invalid input “1.2.3.a” as an address In some cases you may have an address, in others you may have a host name, in some cases either one, so this supports all three options SQL-style single wildcards to end segments: 1.2._._

With CIDR network prefix length using binary format: 0b1.0b10.0b0.0b0/16 Range using inet_aton format: 0x1.0x2.0x0-0xffff With CIDR network prefix length: 1.2.0.0/16

For example, all strings in the list below represent the same IPv4 subnet: Parsing and representation of subnets, either those specified by network prefix length or those specified with ranges of segment values. Parsing of all host name and ipv4/ipv6 address formats in common usage plus some additional formats (see below or see javadoc for the IPAddressString class or godoc for the struct IPAddressString for an extensive list) The IPAddress library was intended to satisfy the following primary goals: Parse String Representations of MAC AddressĬonversion to String Representation of Address Parse String Representation of IP Address or Host Name Java and Go libraries for handling IP addresses and subnets, both IPv4 and IPv6
