Client IP Address

Category: Request

Purpose: Identifies requests that originate from a particular IP address.

Key information:

• Make sure to use CIDR notation.

• Specify multiple IP addresses and/or IP address blocks by delimiting each one with a single space.

  • IPv4 Example: 1.2.3.4 10.20.30.40 matches any requests arriving from either 1.2.3.4 or 10.20.30.40.
  • IPv6 Example: 1:2:3:4:5:6:7:8 10:20:30:40:50:60:70:80 matches any requests arriving from either 1:2:3:4:5:6:7:8 or 10:20:30:40:50:60:70:80.

• The syntax for an IP address block is the base IP address followed by a forward slash and the prefix size.

  • IPv4 Example: 5.5.5.64/26 matches any requests arriving from 5.5.5.64 through 5.5.5.127.

  • IPv6 Example: 1:2:3::0/48 matches any requests arriving from 1:2:3:0:0:0:0:0 through 1:2:3:ffff:ffff:ffff:ffff:ffff.

    IPv6 address blocks should not be fully shortened. As shown in the above example, a trailing 0 is required when shortening fields that consist of 0's.

• The Result option determines whether this condition will be met when a client's IP address is a "match" or does not match the specified IP address(es).

• Due to the manner in which cache settings are tracked, this match condition is incompatible with the following features:

  • Default Internal Max-Age
  • Force Internal Max-Age
  • Ignore Origin No-Cache
  • Internal Max-Stale
  • URL Rewrite
