I want to buy Bulk Proxy IPs from college campus NAT IPs. Are there any providers of such Proxies ? Like a college's public network's IP address or organization's office's free wifi squid based proxies ? Even some cities provide free wifi I think and may be using a NAT.. If someone knows a source or an individual who can sell then please let me know.. any website which sells or any other forum or anywhere whatesoever ? Thanks !
