This report concludes the TI3800 Bachelorproject course, which itself is a compulsory course to gain the Bachelor of Science in Computer Science degree at the Delft University of Technology. This report contains all information about the project that was done over a span of ten weeks at TransIP. The project client was TransIP, a domain- and webhosting company located in Leiden. During these ten weeks the whole DNS backend of TransIP was restructured from a pull-based structure to a push-based one. Furthermore, this report’s goal is to inform the reader about the completed work and the different phases throughout which this was done. The report will also contain recommendations for future work on this project, as the project has gone live at the end of the project and co-employees of TransIP might have to work on the system in the future.
