i will answer the questions in the comments if something is unclear ^^
First it could be that i will change IP on the server, my Internet service provider are unsure if it will happen. i will buy a static ip instead of an dynamic that i use now. i will do it on Monday 2012-10-15
--------- So how will this affect you, you might ask ---------
You go to http://pawncraft.co.uk for forum and use pawncraft.co.uk as an IP in minecraft, that will NOT change. You dont need to do anything.
The thing is, under the address pawncraft.co.uk lays an IP address that is 22.214.171.124
and it is that number that could change.
The internet uses DNS servers that keeps logs of what address that goes to what ip address
there is several out there in the different parts of the world and it can take up to 24 hours before all the DNS nodes in the world get the new numbers.
So what happens if your DNS node hasnt updated and you try to log on? it will just look like the server/forum isnt online.
As a temporary workaround you could connect directly to the new IP numbers, i will post it at www.pfts.se/ip with instructions.
It can also help to follow these instructions to make your computer to clear your own dns cache if you cant connect on monday.
Only type whats between the " ", dont type ".
- Open up a command prompt (Start > Run > "cmd.exe" > OK).
- Type in the command "ipconfig /flushdns"
