GeoDNS should route your British IPTV subscribers to the closest server automatically. UK user goes to London server. US user goes to New York. Simple. But most generic IPTV Reseller Panel implementations use GeoDNS databases that are months or years out of date. Your subscriber in Edinburgh gets routed to a server in Frankfurt because the GeoDNS database thinks Edinburgh is in Germany. Your subscriber in Cardiff goes to Amsterdam. Latency doubles. Performance plummets. A British IPTV-optimized panel uses regularly updated GeoDNS with EDNS Client Subnet support—passing the subscriber's actual IP prefix to the DNS resolver for accurate routing. No guesswork. No outdated databases. Your Edinburgh subscriber hits London. Your Cardiff subscriber hits Manchester. I've watched a reseller cut average latency by 40% simply by switching to a British IPTV panel with accurate GeoDNS. His old generic panel had been routing UK traffic to mainland Europe for two years. He never knew. His subscribers felt every unnecessary millisecond. The pattern is clear: your IPTV Reseller Panel either routes precisely or routes randomly. GeoDNS is only as good as its data. Outdated databases create problems that look like network issues but are actually panel issues.
