Information
This page lists IP ranges where a large number of individual IPs are blocked, but the range is not blocked. This usually means that the range is either a dynamic range with a large number of malicious users or a static range with a large number of open proxies. Rather than continuing to place blocks on individual addresses in a "whack-a-mole" type fashion, it may be advisable to block the entire range for a longer period of time.

Most of the blocks on this page are originated by automatic or tool-assisted proxy detection. These are never 100% effective at detecting proxies, as a proxy server may be offline or overloaded at the time of being checked. Placing a hardblock on the entire range will reduce the "false negative" rate of proxies which are left unblocked for this reason, and will reduce the amount of work that the proxy-detecting bots and tools need to perform. The contributions of each range should still be checked for collateral damage before blocking the range.
