Fix error when checking if IP address is valid

Browse source 
During install in `valid_ip`, we split up the IP address into octets to verify it is valid (each is <= 255).

This validation was broken in #2743 when a variable usage was quoted where it should have stayed unquoted:
```
./automated install/basic-install.sh: line 942: [[: 192.241.211.120: syntax error: invalid arithmetic operator (error token is ".241.211.120")
```

Due to this error, `127.0.0.1` would be used instead of the requested IP address. Also, this prevented the user from entering a custom DNS server as it would be marked as an invalid IP address.
