Security extensions were added to the DNS protocol as a means of countering malicious attacks such as cache poisoning, domain hijacking, and man-in-the-middle attacks.  The extensions are described in detail in RFC 4033 (Introduction and Requirements), RFC 4034 (Resource Records), and RFC 4035 (Protocol Modifications).  Understanding what DNSSEC is and why it's important is well covered elsewhere -- whitepapers, research, etc at http://www.dnssec.net and there's a nice implementation tutorial at http://www.dyndns.com/support/kb/implementing_dnssec.html -- so we'll focus here on the DNSSEC implementation details as it pertains to GTM.

Virtual Servers are accessed by user friendly name. In some cases you will want to know which Virtual Servers are using a given address. This script takes as input a wildcard spec for the address:port of a virtual server and lists the address:port and name for all matches. 

Remote authorization for ldap was first introduced in version 9.4.  Now, however, in v10, the feature has been expanded to include radius and tacacs+.  In this article, I'll walk through the tacacs+ server configuration and the remoterole configuration on the BIG-IP required to get remote authorization working.

I've been dying to spend some time digging in to python, iControl, & GTM--why not combine all three into a single article?  Done.  This article will walk you through the iControl methods (in python, yea!) necessary to grab wideIP and pool statistics from the GTM.

The Fast HTTP profile is a configuration tool designed to speed up certain types of HTTP connections. This profile combines selected features from the TCP, HTTP, and OneConnect profiles into a single profile that is optimized for the best possible network performance. When you associate this profile with a virtual server, the virtual server processes traffic packet-by-packet, and at a significantly higher speed.  With BIG-IP version 10, cookie persistence is now compatible with the FastHTTP profile.
