How does GeoDNS work?

Latency is the key differentiator when it comes to application performance on the internet. Reduced latency accelerates the delivery of apps. DNS resolving is the first step towards application delivery and it involves a series of steps. Prior to Anycast DNS, the DNS servers responsible for resolving users’ DNS requests were sitting continents away from many users, contributing to the high latency and slow delivery of applications.


How does a DNS work?

DNS resolution is the first step taken to form an internet connection. This includes when any device is being used to access a website or any type of internet-enabled application, such as e-commerce, CRM, or food delivery. These applications are connected to the internet via IP-backbone, which is typically controlled by a protocol named BGP (Border Gateway Protocol). Each application has a unique numbering schema on the internet, referred to as IP address.


How to monitor DNS query response time

DNS (Domain Name System) servers translate standard language web addresses to their actual IP addresses for network access. DNS response time is the time it takes a Domain Name Server to receive the request for a domain name’s IP address, process it, and return the IP address to the browser or application requesting it. When it comes to DNS response times, the lower the better, and generally values less than 100ms are considered to be in the acceptable range (depending on the application).

3 Steps to Prepare DNS Changes for a Data Center Migration

Data center and cloud migrations often require changing IP addresses of your servers and application end points. These changes require careful planning and precise execution in order to minimize downtime. Typically, this is executed by manually searching your DNS server’s configuration for each server that is migrating.
