The main use here is when sending OSC messages using `python-osc`, it seems to
work better if you use the numerical address for the target device. On my LAN
I stick to IPV4, hence `AF_INET` and `SOCK_DGRAM`. Then `info[0][4][0]` drills
down into the returned structure to find the IP address.

```python
#!/usr/bin/env python
import socket
import sys
for arg in sys.argv[1:]:
  info = socket.getaddrinfo(arg,0,socket.AF_INET,socket.SOCK_DGRAM)
  if len(info) > 0:
    ip = info[0][4][0]
    print(ip)
  else:
    print(f"{arg}: Not found")
```
