I am looking for a way to return a boolean result for a column finding ip addresses in a url as `true` and no ip address in url as `false`

```
    col1
0   http://197.248.5.23/
1   https://197.248.5.23/
2   http://179.12.170.88/pdf/forced/jit/
3   http://tel:888
4   http://li

```

Desired output:

```
    col1                                   contains_ip
0   http://197.248.5.23/                   True
1   https://197.248.5.23/                  True
2   http://179.12.170.88/pdf/forced/jit/   True
3   http://tel:888                         False
4   http://li                              False

```
