if u willing to host it on your computer at home or in datacenter? i guess you are doing at home. then u need to register ur ip as domain (free - l2kalvitis.bubulis.com or payd - l2superserveris.lv, but i advise u not to take the free one), then u need make an register page (apache+web template u can find on this forum, for the safety i suggest u to host ur website not on the same computer where is ur l2 server located), open 2106 and 7777 ports on firewall, make an patched system folder and upload it on your webiste to allow people to conenct, advertise ur server on forums+voting sites and thats all.
