Olá pessoal, tenho algumas dúvidas quanto a esta análise do Zenmap...

A primeira análise é do meu modem... (10.1.1.1)

Interesting ports on 10.1.1.1:
Not shown: 1711 closed ports
PORT STATE SERVICE VERSION
21/tcp open ftp?
23/tcp open telnet?
80/tcp open http?
2 services unrecognized despite returning data. If you know the service/version, please submit the following fingerprints at

Porque o programa não reconheceu dois serviços?
