Mastering DNS: Anycast, GeoDNS, and TTL Optimization
Low-latency DNS strategies to improve TTFB and global application responsiveness.
The Impact of DNS Latency on User Experience
User experience begins with a DNS lookup. If your DNS provider is slow, your website will feel sluggish even if your server is fast. AIHostOn utilizes a global Anycast DNS network, which ensures that DNS queries are answered by the node closest to the user. This significantly reduces Time to First Byte (TTFB) and provides a faster initial connection for your global audience.
Geo-Steering and High Availability
GeoDNS allows you to serve different IP addresses based on the user's location. For example, a user in Tokyo can be directed to your Japan data center, while a user in London goes to your UK nodes. This logic, combined with our health-check API, ensures that users are always routed to the nearest *healthy* instance, providing both performance and redundancy in a single solution.
