Python netifaces and scapy: Getting meaningful Interface-names and full IP-Adresses-/Netmask-Information

Using Windows:

  • scapy reads:
    • meaningful interface-names
    • ip-address
    • but no netmask
  • netifaces reads:
    • full Ethernet/IP/IPv6-Information
    • but no meaningful interface-names

Mixing both, provides everything needed.

  1. Netifaces only
    2. from netifaces import AF_INET, AF_INET6, AF_LINK
import netifaces

for i in netifaces.interfaces():
   niif=netifaces.ifaddresses(i)
   print("i",i)
   for k,v in niif.items():
     print("Key",k)
     if k==AF_LINK:
       print("LINK:",v)
     if k==AF_INET:
       print("IPv4",v)
     if k==AF_INET6:
       print("IPv6",v)
   print()

    >>> for i in netifaces.interfaces():
...    niif=netifaces.ifaddresses(i)
...    print("i",i)
...    for k,v in niif.items():
...      print("Key",k)
...      if k==AF_LINK:
...        print("LINK:",v)
...      if k==AF_INET:
...        print("IPv4",v)
...      if k==AF_INET6:
...        print("IPv6",v)
...    print()
...

  2. Adding Scapy to get meaningful interface names
    3. from scapy.all import *

for i in ifaces.data.keys():
  print(i)
  iface = ifaces.data[i]
  wname = iface.data['netid']
  addresses = netifaces.ifaddresses(i)
  af_inet = [{"addr": "0.0.0.0", "netmask": "0.0.0.0", "broadcast": "0.0.0.0"}]
  if AF_INET in addresses:
    af_inet = netifaces.ifaddresses(i)[AF_INET]
  print(wname,af_inet)

    >>> for i in ifaces.data.keys():
...   print(i)
...   iface = ifaces.data[i]
...   wname = iface.data['netid']
...   addresses = netifaces.ifaddresses(i)
...   af_inet = [{"addr": "0.0.0.0", "netmask": "0.0.0.0", "broadcast": "0.0.0.0"}]
...   if AF_INET in addresses:
...     af_inet = netifaces.ifaddresses(i)[AF_INET]
...   print(wname,af_inet)
