Check DNS Propagation Status

Verify whether recent DNS changes have propagated and the new records are live.

After updating DNS records, changes do not take effect instantly. Propagation can take anywhere from minutes to 48 hours depending on TTL values and caching. During this window, some users see the old records while others see the new ones, which makes debugging confusing.

The lookup_dns skill lets you check the current state of DNS records to verify whether your changes have propagated. Compare the returned records against your intended configuration to confirm the update is live. This is faster and more reliable than waiting and hoping.
