You go to minecraftserverlist.com
Check on websites such as planet minecraft or other sources to find the latest survival servers that have been pinged and work.
You need to google it there are thousands of servers.
IP to the question is:badcheese.com:25565
There are not many Beta servers up at the moment, but the ones that are can be found with Google. engamma.dyndns.org
To find good Minecraft servers check out "Planet Minecraft" is you look under "Servers" you can hit "Top rated!" for the best of the best. But I personally recommend PabiCarft. It is the only server I ever play on. The ip is: pabicraft.no-ip.orgAnd its website is: pabicraft.enjin.com
No, there is not any good servers for Minecraft 1.6.6. In fact, there are no more 1.6.6 servers at all. There are only updated servers. My recamendation is for you to update minecraft. All of the servers, or the most active, always update.
forget the question its easy theres nuke server and exploding tnt server or find some other servers in youtube the servers got site in youtube there own site is awesome so check the server in youtube or search it to play minecraft
There are many, many thousands. You can go on websites such as Planet Minecraft or Minecraft Server List to find some that you would like.
Either the Minecraft Forums, Google it or PlanetMinecraft
no you need minecraft beta to play beta servers
If you go onto the site "PlanetMinecraft" then hit "Servers" on the horizontal menu. Then click on "servers" then "Top List!" you can see the top servers on the biggest Minecraft site.
