Readme
ip-address
ip-address
is a library for validating and manipulating IPv4 and IPv6
addresses in JavaScript.
Migrating from 6.x to 7.x
ip-address
was rewritten in TypeScript for version 7. If you were using
version 6 you'll need to make these changes to upgrade:
- Instead of checking
isValid()
, which has been removed, you'll need to use atry
/catch
if you're accepting unknown input. This made the TypeScript types substantially easier as well as allowed the use of anAddressError
class which will contain aparseMessage
if an error occurred in the parsing step. - Instead of using the
error
,parseError
, andvalid
attributes you'll need to use themessage
andparseMessage
of the thrownAddressError
.

Examples
var Address6 = require('ip-address').Address6;
var address = new Address6('2001:0:ce49:7601:e866:efff:62c3:fffe');
var teredo = address.inspectTeredo();
teredo.client4; // '157.60.0.1'
Features
- Usable via CommonJS or ESM
- Parsing of all IPv6 notations
- Parsing of IPv6 addresses and ports from URLs with
Address6.fromURL(url)
- Validity checking
- Decoding of the Teredo information in an address
- Whether one address is a valid subnet of another
- What special properties a given address has (multicast prefix, unique local address prefix, etc.)
- Number of subnets of a certain size in a given address
- Display methods
- Hex, binary, and decimal
- Canonical form
- Correct form
- IPv4-compatible (i.e.
::ffff:192.168.0.1
)
- Works in node and the browser (with browserify)
- ~1,600 test cases
