It appears that bitcoin addresses using p2sh keys have a different prefix to that of normal bitcoin addresses. Do other altcoins such as litecoin, peercoin, dogecoin etc include this functionality?

Upon looking at the source of a number of altcoins I have found that p2sh keys are built into all the ones I checked.

For P2SH, the first address byte will be:

bitcoin: '05'
litecoin: '05'
peercoin: '75'
dogecoin: '16'
beavercoin: '05'
freicoin: '05'
protoshares: '05'
megacoin: '05'
primecoin: '53'
auroracoin: '05'

The tricky bit about this is that you can't nessesarily tell what network a P2SH address belongs to like you can with normal addresses.

The reason I wanted to know is so I could collate the version numbers for my project:
