DNS settings affect how your customers connect to your streams. Your IPTV reseller panel should allow some flexibility here.
Your IPTV panel might let you configure custom DNS servers for your customers. This can improve connection speeds and bypass ISP throttling.
Here's the thing: as an IPTV reseller, you might not control DNS directly, but you can recommend settings to your customers. A panel that supports custom DNS makes this easier.
What actually works is choosing a panel that doesn't lock you into a specific DNS. You should be able to change the DNS servers associated with your account—or at least provide guidance to customers.
I've seen panels where DNS was hardcoded. Customers had to manually change their device settings to get optimal performance. That's not a great experience.
The pattern that keeps showing up is resellers ignoring DNS optimization. They assume it doesn't matter, but it can significantly impact buffering and load times.
That said, DNS changes are not for everyone. Some customers prefer the default settings, and that's fine. But offering options shows that you're considerate of their needs.
Another aspect is DNS security. Some panels offer DNS-over-HTTPS (DoH) for encrypted lookups. This protects customer privacy and prevents ISP tracking.
Your IPTV panel should also provide DNS diagnostics. If a customer complains about slow connections, you can check their DNS resolution time and suggest improvements.
Ultimately, DNS is a technical detail that affects user experience. A panel that handles DNS well gives you another tool to improve your service.
