At first, 192.168.1.101 is a local ip address (dynamic one), to find out your real ip address search "find my ip" on google. That will be your static ip address. But most of the ISP (internet service providers) change this static ip address, so that the users will not be able to host a site (Because they will charge you more for allocating you a static ip address).
Second point- If you manage to host a site at your static ip address, you can find the relevant information here or you can skip through it and claim a namespace (http://www.noip.com/)
