Oliver, who was previously deputy editor of .net between 2000 and 2004, oversaw the redevelopment of the .net , having been involved with the redesign of sister title Practical Web Design, and will be joined by new art editor Chris Bates.
Future said the print redesign would retain the title's mix of features, news and reviews, but would now include a number of new sections, comprising an exclusive monthly interview, 30-pages of tutorials, regular opinion pieces from expert web designers and Feed, a 12-page section on the best new websites, podcasts and forthcoming events.
Kelley Corten, publisher of .net, said: "With the appointment of Dan as editor, I expect the magazine to go from strength to strength. Dan has a real passion for the internet, and he'll ensure that .net continues to set the agenda and provide its readers with insightful features and tutorials."
Coinciding with the redesign, the August issue of .net will be dedicated to web page redesign, and offer tips on how to spruce up cluttered homepages and offer increased usability.
The edition will also feature an interview with British hacker Gary McKinnon, and an article on internet censorship in China.
Oliver said: "We plan to celebrate the best the internet has to offer, via a redesigned magazine, a new website and the first .net podcast, which will launch later this year."
The title, which celebrated its 150th issue in May, has a circulation of 13,801.
In June, Future Publishing appointed former Clear Channel chief executive Stevie Spring as chief executive, with a brief to look at refreshing the publisher's portfolio of magazines and websites.
