Purpose

This how to guide explains what the multiple IPs referenced in the JIRA application logs refer to. For example:

2016-03-25 10:35:13,626 http-nio-8080-exec-22 ERROR captain-planet 635x404x1 7nuhc0 131.103.28.11,10.0.1.83 /secure/Dashboard.jspa [c.a.g.r.internal.http.HttpClientFetcher] Unable to retrieve response

Solution

• This is a set of IP addresses that may include the proxy forwarded address - this comes from the X-Forwarded-For header.
• Otherwise it includes the remote IP address, which is the IP address of the client or last proxy that sent the request.

• It can also be null if neither of those exist.

• In this example, 131.103.28.11 is from the X-Forwarded-For header, and 10.0.1.83 is the remote IP address.
