DNS and the Internet of Things : Outlining the challenges faced by DNS in the Internet of Things

Sammanfattning: This thesis work consists of a literature study where different aspects of DNS and the Internet of Things have been researched. A functional naming and service identification method is an essential part in making the IoT global, and DNS is the current method of naming devices on the Internet. The study looks into some challenges DNS will encounter, namely functionality, security and availability. This report concludes that a multicast DNS (mDNS) based solution designed for constrained networks is advantageous. This is despite the limited security that is currently available for such a solution. In the future, it is important that security has top priority, as there are currently limited means of security in DNS. Further study is needed when it comes to availability and how name resolving would work with constrained devices that utilise sleep mode.
