What is the difference between class a, class b, class c proxies?

as i will need proxies (i've never used before) as i run whitehat sites for my income.

could anyone explain to me whats the difference?

just so i know what i'm looking for?

Thanks

Try Wikipedia

Great stuff thats helped alot

There is no sense in looking for a proxy in a "class a b c" network.
This sort of adressing is old and obsolete anyway and it doesn't mean anything if a proxy is in one or the other.

You maybe mean L1 L2 L3 proxies, the number 1 means high anonymity and 3 is no anonymity and L2 leaks the fact you are using a proxy.

You might just say what you want to do, then it is easier to point you to possible solutions.
