Nmap seem always showing service names (using an "nmap-services" file for that). I would like if nmap would show the port numbers. So:
```
1.2.3.4.sunwebadmin
1.2.3.4.teradataordbms
1.2.3.4.tproxy
1.2.3.4.trivnet1
```
For example, a similar tool, lsof, has the flag `-N` for that.
Can I somehow do the same with nmap?
