Almost all network connections require a Domain Name System (DNS) lookup, which converts simple web addresses into computer-readable IP addresses. Until recently, network providers haven’t had to worry about the latency of DNS as it can hide within the higher latency of the radio access network (RAN) - but this changes with 5G, where RAN latency drops by an order of magnitude. Additionally, DNS has huge potential to deliver the fastest local content with the advent of true edge computing, but typical DNS architectures are not designed for this. Furthermore, with 5G’s capacity to support a minimum of one million devices per square kilometre, the IoT world is set to explode. These devices - which often lack the CPU or RAM necessary for on-device protection - are already being compromised for use in botnets, and traditional security methods are not sufficient to provide protection from cyberattackers. Without re-invention, the current architecture used for DNS will adversely affect user experience and locality of content delivery, impact time-critical machine-to-machine IoT connections and leave devices vulnerable to cyber threats. This talk discusses how DNS can make use of new technologies such as edge computing and cloud-native deployment architectures to enable 5G use-cases around latency, speed and security.
