what is the default unity master server's IP and port? where can i find the info about it on unity3d.com? can we use it for small commercial games?
Master Server info: 72.52.207.14:23466
If someone still trying to use unity’s master server and is failing to connect with the address given in first answer, try this ip address 67.225.180.24, it works for me.
regarding port, various ports work for me i usually use the one mentioned in the first answer 23466.
Im pretty sure that Unity doesn't have a server that we can use, however there is an alternative you can use. Try looking up Smartfox on google. Its very good for Game servers!
Good luck!
