DNS
What Is DNS and Why It Matters
A simple explanation of DNS and website loading speed.
DNS works like a directory that converts domain names into IP addresses. Without DNS, browsers would not know where to find websites.
Slow DNS can make websites feel delayed before they start loading, even when your download speed is good.
Trying a trusted DNS provider can sometimes improve browsing response, but it will not increase your raw internet speed.
Quick checklist
- Run a fresh test after changing one setting.
- Compare Wi-Fi and Ethernet when possible.
- Check download, upload, ping and jitter together.
