Class IPFilterRules

java.lang.Object

org.apache.nutch.protocol.okhttp.IPFilterRules

public class IPFilterRules
extends Object

Optionally limit or block connections to IP address ranges (localhost/loopback or site-local addresses, subnet ranges given in CIDR notation, or single IP addresses). IP filter rules are built from two Nutch properties:

• http.filter.ipaddress.include defines all allowed IP ranges. If not defined or empty all IP addresses (and not explicitly excluded) are allowed.
• http.filter.ipaddress.exclude defines excluded IP address ranges.

IP ranges can be defined as

• IP address, e.g. 127.0.0.1 or ::1 (IPv6)
• CIDR notation, e.g. 192.168.0.0/16 or fd00::/8
• localhost or loopback applies to all IP addresses for which InetAddress.isLoopbackAddress() is true
• sitelocal applies to all IP addresses for which InetAddress.isSiteLocalAddress() is true

Multiple IP ranges are separated by a comma, e.g. loopback,sitelocal,fd00::/8
