Hi guys, I was looking up L4D2 server cvars and came across this on a couple different pages:

setmaster enable setmaster add 68.142.72.250:27011 setmaster add 72.165.61.189:27011

I was hoping someone could explain to me exactly what this does? I looked it up online, but the typical cvar descriptions are very generic...anything more in-depth would be greatly appreciated.

For example, what are those IP addresses to/for? Would I replace that with my own server's IP address or are those for some master server and if that is the case, what does the master server do and what advantage does adding these cvars to my server.cfg does this offer?

Thanks in advance for any help!
