Can I assume taht a SOCKS server is normally placed within a DMZ

Can I also assume that SOCKS normally operates as a reverse proxy

Does SOCKS have the ability to turn on or off the tunneling (and in effect act  as port forwarding

Can SOCKS reject IP's

Thanks

It's not part of the RFC, so yes and no. This is the same for most protocols, TCP for example has no mandate for IP or MAC address filtering, but it's a feature of many products.
SOCKS is a protocol, and when you create a server based on that protocol you can tack on other features.
SOCKS proxies are typically, I think anyway, FWD proxies, when you are attempting to get out on one protocol to avoid being detected or seen as another protocol. SOCKS is a tunnel, and if you tunnel out port 80 to a SOCKS proxy on the internet, you are doing the FWD motion. If someone connect to a SOCKS proxy to get into your network, then it's a reverse proxy. The FWD/REV thing is relative, they are the same thing, only direction dictates the name. SOCKS proxies are mainly used as anonymizers, or restriction by-passes.
The other difference between a SOCKS and an HTTP proxy is that http doesn't wrap the requests in a secure tunnel, a socks connection is encrypted end to end so it can't be sniffed, unlike an http proxy.
