About the project

Zytrax is a resource that positions itself as a center for training and technical support in the field of network technologies. The company claims to focus on acquiring and imparting knowledge rather than simply delivering courses. Particular emphasis is placed on DNS and LDAP, where the company's experts consider their knowledge unique to the industry.

The site has existed since 1994, which is confirmed by the copyright of ZyTrax, Inc. , however, the modification date of the page indicates February 2022, although the current date on the site is February 2026. This creates a strange picture: the project seems to be working, but the content may be outdated or simply not updated in a long time.

Main directions

Zytrax's activities are divided into several clear blocks:

  • Training (Zytrax Training). They sell courses on DNS and LDAP here. The authors' key idea is that they convey the experts' passion for the subject, rather than dry theory. Students must not only know the material, but understand it.
  • Technical section (Tech Stuff). A collection of useful materials that the team has collected over the years. This is a free service for the community. The authors ask to report errors or omissions - they promise to respond in the same tone in which the letter arrived.
  • Open Guides. The Rocket Scientist Guides series is dedicated to open source software. The first guide has already become popular and is used hundreds of thousands of times a month. The project also mentions the transition of some tools (for example, Ethereal, which became Wireshark) to the Apache Foundation.
  • Tools and utilities. The site contains converters (Decgt; Hexgt; Bin), reference books on HTML entities, instructions for setting up Apache (SSI, environment variables), as well as materials on determining identifiers for browsers and mobile devices.

Features of the site

The site is distinguished by a rather direct and sometimes cynical style of communication with the user. The authors openly criticize modern standards: they call HTML 5 a joke, and contrast the seriousness of the industry with the fun of the past (Sniffing the glue that holds the Internet together).

There are also technical nuances. The site warns that if the browser does not comply with W3C standards, the experience may not be optimal. There is also mention of hosting moving to some distant land to improve service. In the Other Stuff section you can find information about why the company is called that way, although the text of this question is cut off in the provided fragment.

An interesting point is the attitude towards security. There is a call to publish SPF records to combat spam and identity theft, but the action itself requires clicking on buttons, which in the text are simply called SPF button without a detailed description of the functionality.

Contact information

On the main page there are links for communication: mail us, mail this page, contact us.However, there are no specific email addresses or phone numbers in the text provided. Only the general principle of feedback is mentioned: if you find an error in technical materials, you need to write to them by email.
