What are the IDs for the various Ethereum chains? [duplicate]

Question

I'm looking to find the chain ID's for each network (homestead, etc.). I believe the v-value of signatures is associated with these to some extent.

I'm also under the impression that the ropsten ID is 3, if that gives any context to what I'm looking for.
