ifaddr 0.1.6

Enumerates all IP addresses on all network adapters of the system.

ifaddr is a small Python library that allows you to find all the IP addresses of the computer. It is tested on Linux, OS X, and Windows. Other BSD derivatives like OpenBSD, FreeBSD, and NetBSD should work too, but I haven’t personally tested those.

This library is open source and released under the MIT License.

You can install it with pip install ifaddr. It doesn’t need to compile anything, so there shouldn’t be any surprises. Even on Windows.

Let’s get going!

import ifaddr

adapters = ifaddr.get_adapters()

for adapter in adapters:
    print "IPs of network adapter " + adapter.nice_name
    for ip in adapter.ips:
        print "   %s/%s" % (ip.ip, ip.network_prefix)

This will print:

IPs of network adapter H5321 gw Mobile Broadband Driver
   IP ('fe80::9:ebdf:30ab:39a3', 0L, 17L)/64
   IP 169.254.57.163/16
IPs of network adapter Intel(R) Centrino(R) Advanced-N 6205
   IP ('fe80::481f:3c9d:c3f6:93f8', 0L, 12L)/64
   IP 192.168.0.51/24
IPs of network adapter Intel(R) 82579LM Gigabit Network Connection
   IP ('fe80::85cd:e07e:4f7a:6aa6', 0L, 11L)/64
   IP 192.168.0.53/24
IPs of network adapter Software Loopback Interface 1
   IP ('::1', 0L, 0L)/128
   IP 127.0.0.1/8

You get both IPv4 and IPv6 addresses. The later complete with flowinfo and scope_id.

Alternatives

Alastair Houghton develops netifaces which can do everything this library can, and more. The only drawback is that it needs to be compiled, which can make the installation difficult.
