IPv4 and IPv6 are the two versions of IP. IPv4 was first released in 1983 and is currently widely used as an IP address for a variety of systems. It aids in the identification of systems in a network through the use of an address. The 32-bit address, which may store multiple addresses, is employed. Despite this, it is the most widely used internet protocol, controlling the vast bulk of internet traffic. IPv6 was created in 1994 and is referred to as the "next generation" protocol.

HAProxy is one of the world’s most innovative and highest-performing load balancing solutions. The load balancer is critical for enabling high availability and supporting the dynamic scaling of infrastructure within modern applications. Because of its importance, engineers need tools that can quickly and effectively diagnose any problems with the load balancer if they arise.

Learn how to test your HAProxy Configuration. Properly testing your HAProxy configuration file is a simple, yet crucial part of administering your load balancer. Remembering to run one simple command after making a change to your configuration file can save you from unintentionally stopping your load balancer and bringing down your services.

It has been a while since I have been excited to write about encrypted tunnels. It might be the sheer pain of troubleshooting old technologies, or countless hours of falling down the rabbit hole of a project’s source code, that always motivated me to pursue a better alternative (without much luck). However, I believe luck is finally on my side.

There’s something that humans and machines have in common, and no, it’s not the disappointment suffered by the final season of Game of Thrones, or, well, at least not only that. What we have in common is that we need protection. You know, animals need it too, and plants, but if you’ve gotten this far, it seems that you’re interested in computers, networks and all these pretty modern “geek” things, so today we’ll talk about that kind of protection.

The meanings behind job titles can be an elusive thing in that they might only make sense to the people actually in the roles. Take networking jobs. It’s pretty common for people to think some titles can be used interchangeably, and that depending on where you work, a job may have a different name. In some cases, even IT professionals believe that the network specialist vs engineer are jobs are really the same responsibilities.

With so many of us working from home full time for the last 16 months, VPNs have become essential tools for companies to keep their staff working in a safe environment. What we mean by “safe” is mainly about your online presence whilst performing daily tasks for your job.

HTTP/2 (originally named HTTP/2.0) was a major revision of the HTTP network protocol used by the World Wide Web published in 2015. Indeed, those in the Citrix/EUC ecosystem may remember Marius Sandbu investigating the benefits of HTTP/2 for NetScaler, Microsoft IIS, and Storefront users back in 2015/6. HTTP/2 was the first new version of HTTP since HTTP/1.1, which itself was standardized in RFC 2068 in 1997.
