Out on May 8, it will feature in-depth interviews with web luminaries such as designer Jeffrey Zeldman and Ruby on Rails inventor David Heinemeier Hansson, who will look back on the history of the internet since .net was launched in 1995.
The special edition, which includes a covermount of 150 free web tools, will also look at the "unsung heroes" of the web, and the impact they have had on people's daily lives. There will also be 150 prizes to give away, including MP3 players, USB sticks and SkypeOUT minutes.
Lisa Jones, editor of .net, said: "Our magazine has been a constant companion for web users, as the internet has transformed from niche geek interest to part of everyday life.
"Today, .net is the best-selling magazine for web designers, developers and anyone who is passionate about the web."
Sold under the name Web Builder in the US, .net has built a reputation for using strong images, which sometimes feature on the magazine's back page in favour of traditional ads.
The magazine has a circulation of 13,801. Its previous editors include Paul Douglas, Dave Taylor and Richard Longhurst.
