Questions about the DNS test
How does browser DNS comparison work?
The tool sends real encrypted DNS-over-HTTPS queries to major public providers and times each response.
How is DoH different from my router DNS?
The browser test compares public DoH providers over port 443. Your devices usually use the DNS set in the router or supplied by the provider.
Does changing DNS increase download speed?
No. DNS affects opening new sites and resolving addresses, not the bandwidth in Mbps supplied by your plan.
How does SignallQ Android test DNS?
It evaluates the local resolver, compares it with DoH services, and flags provider DNS slowness or failures.
