HTTP proxies are good, but I normally use socks personally. For the program I use with my browser, they're more reliable than normal proxies. Thank you for the info, I think I'll try to scan that way though.

But what I truly want to know is with the socks IPs, how do you scan accurately for high ports? Being as there are so many of them and no high ports are common except for 50050, 50033, and 32167. Do you just scan for IPs and then portsccan the ones you find? Do they come from sites?
