Resolve a domain name over the SIM connection
Resolve a domain name over the SIM's data connection and measure how long the carrier's DNS takes to answer.
DNS is the directory that turns a domain name into a server's IP address. Check that the carrier's DNS answers correctly and track resolution time: slow resolution is a frequent hidden cause of slow mobile experiences.
Parameters
| Parameter | Required | Description |
|---|---|---|
| Host | Yes | Domain to resolve, for example kapptivate.com. |
| DNS override | No | Query specific DNS servers instead of the carrier's. |
| DNS Lookup should fail | No | Invert the verdict, for domains that must be blocked. |
Plus the shared connection settings.
