what i must select in no ip host registration for static ip it have this choises :Host Type:

DNS Host (A)

DNS Host (Round Robin)

DNS Alias (CNAME)

Port 80 Redirect

Web Redirect 

The first one.DNS Host (A)

i selected DNS Host (A) and i seted my ip in l2loathing.no-ip.org but when i make online my server with external ip l2loathing.no-ip.org and the other ppl try login says pass incorect why?

Maybe the registration is not auto..

Or maybe you didn`t change host/l2.ini files.

i dont change ini i changed host at c:/windows.... and auto acc is enabled but when i use normal ip like 82.100.00.200 the ppl can login normal in server...

Well you need to download a program too in the no-ip site did you download it? :P

yes i have acc and i have make a host with choise dns.(a) then i run the program i set mail and pass i i check my host file in program(like xxx.no-ip.org) it says the ip xxx.xxx.xxx have up grade to xxx.no-ip.org and then i go to server.properties on external host i set xxx.no-ip.org and i run the server when server is online says internal host 127.0.0.1 and xternal xxx.no-ip.org but when i set to my host xxx.no-ip.org l2auth.... and i try login says me pass is incorect.. but if i set o external ip an ip like 123.125.123 the ppl login normal can anyone giveme some screenshoots to see what i do incorect to no-ip..

Well maybe if you change the l2.ini it will work  because i think you did it right with the no-ip if you cant set the l2.ini(is kamael and cant modified it ) i will upload it later for you just say it.

but i have interlude server i deen the ppl want to conect to use only host not patch.. :/

The diference between patch and host is that if you have a normal server without anything "costume" you can use host else only patch try with pach you will not gonna loose something.

2 net cafes that will suport my server will setup my server in theur nets only if its with host...

what is the diference of host and l2 ini adress? if i set the l2loath.no-ip.com l2ath.... in host what is the diference?

guyz if i make a lan with 2 pcs and the 1st pc share his conexion with the second (i mean the 1st pc is server) then i think the second pc will have static ip it will not change after server conection rr is that true?

no the ip will change normally if its dynamic
