Random IP Address Header

Summary: A Burp Suite extension called Random IP Address Header automatically generates fake IPv6 and IPv4 source address headers to evade WAF filtering. Its author, Andres Tarasco Acuna, lists version 1.0 with a last update of 01 July 2014, and the page says it can help when attacking sites with Imperva WAF or evading WAF rules behind Akamai CDN.

Bottom line: A tool for slipping past Imperva and Akamai WAF filtering has sat in the Burp BApp Store since 2014, and PortSwigger states it makes no warranty about third-party extensions' quality or usefulness - so WAF rules tuned to source addresses are only as good as their assumptions about who controls the header.
