I have the same problem. I cannot do anything, and even though I have a dynamic IP, he just re-resolves it, finds my IP, and starts DDoSing me again.
Please fix this issue.
Please provide examples of these incidents so they can be researched further and investigated. I am subscribed to this thread so I can follow up.
Luckily most IP addresses change fairly often which completely prevents them from attacking you so long as they can't obtain it again.
The problem is that they can obtain it again if you're using Skype, so it needs to be fixed
Get your IP and do what with it? The IP address you've gotten, that is the IP address of the server, is as far as you're going to get. You are not directly connected to the other user when using Skype, you each connect to a "supernode" (server) that passes the communication between the users.
Most ISP issue dynamic IP and block common ports like 80, 25, and some other ones used for popular protocols. Most of the time, your IP resets and your ISP issues you a new IP when your router reconnects. Of course that's assuming you have a dynamic IP.
Basically everyone who has a fully open chat connection constantly deals with spam like this. Either set Skype to "people in my Contact list only" or block these guys individually and move on.
I think you're misunderstanding the situation. Any user, having added you or not, is able to retrieve your IP address through a medium completely separate from Skype. The only information they need is your username. No prior contact is needed
With your Skype username "tamim.sarkar", I was just able to find all recent IP addresses you've used to sign in to Skype.
This might not seem a problem for you as you don't have anyone targetting you, but for users on online communities this is a serious problem as knocking people offline is now common occurence

this is so wrong it is not even funny
supernodes DO NOT carry VoIP traffic
most sessions between Skype users are over direct, peer-to-peer connections, and the IP address returned by this annoying Skype Resolver hacker tool is the current public IP of the Skype user that is signed in
