[Elemag](https://stackoverflow.com/users/2436840/elemag) on gave a quick solution on StackOverflow on [how to determine IP addresses with multiple NICS](https://stackoverflow.com/questions/270745/how-do-i-determine-all-of-my-ip-addresses-when-i-have-multiple-nics).
|
|
|
|
His one-line solution:
|
|
|
|
```python
|
|
import netifaces
|
|
ip_addresses = [netifaces.ifaddresses(iface)[netifaces.AF_INET][0]['addr'] for iface in netifaces.interfaces() if netifaces.AF_INET in netifaces.ifaddresses(iface)]
|
|
```
|
|
|
|
Expanded out to see what is happening
|
|
|
|
```python
|
|
import netifaces
|
|
interface_list = netifaces.interfaces()
|
|
# Get addresses, netmask, etc. information
|
|
address_entries = (netifaces.ifaddresses(iface) for iface in interface_list)
|
|
# Only pay attention to ipv4 address types
|
|
ipv4_address_entries = (address[netifaces.AF_INET] for address in address_entries if netifaces.AF_INET in address)
|
|
# Since multiple addresses can be associated, only look at the first ip address
|
|
ipv4_addresses = [address[0]['addr'] for address in ipv4_address_entries]
|
|
```
|
|
|
|
We can easily adjust this to ask for IPv6 addresses by using `netifaces.AF_INET6` instead.
|
|
|
|
```python
|
|
import netifaces
|
|
interface_list = netifaces.interfaces()
|
|
# Get addresses, netmask, etc. information
|
|
address_entries = (netifaces.ifaddresses(iface) for iface in interface_list)
|
|
# Only pay attention to ipv6 address types
|
|
ipv6_address_entries = (address[netifaces.AF_INET6] for address in address_entries if netifaces.AF_INET6 in address)
|
|
# Since multiple addresses can be associated, only look at the first ip address
|
|
ipv6_addresses = [address[0]['addr'] for address in ipv6_address_entries]
|
|
```
