F5 Networks - BigIP Market Penetration (by IP Address)
December 1st, 2002

F5 is a company specializing in networking and security products. F5's load balancer is finding its way into many organizations. This report leverages returned information found in the HTTP protocol allowing us to detect the existence of F5 products, and thus report on the market penetration rate of these products.

The detection of F5 is done via two basic mechanisms:

1. The server signature may return back an indicator of "BigIP".

$ telnet 80 Trying Connected to Escape character is '^]'. GET / HTTP/1.0 HTTP/1.0 301 Moved Permanently Location: Server: BigIP Connection: close Content-Length: 0 Connection closed by foreign host. $

2. The cookies returned back may indicate a load balancer is in use.

$ telnet 80 Trying Connected to Escape character is '^]'. GET / HTTP/1.0 HTTP/1.0 301 Moved Permanently Content-Type: text/html; charset=UTF-8 Location: Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Sat, 20 Jun 2015 19:28:31 GMT Connection: close Content-Length: 151 Set-Cookie: BIGipServerWebCluster_4=1137223872.20480.0000; path=/ Connection closed by foreign host. $

The following graph and table demonstrates the percentage of IP addresses that are indicating one of the above mentioned signatures. The sample size (the # of distinct IP addresses hosting a web server of some sort) is: 1,976,033.
