DNS TTL Checker

Inspect current DNS record values and their cache lifetime in seconds.

This live lookup sends only the IP address or hostname you enter to the named public lookup service. Do not submit private hostnames or confidential infrastructure details.

About the DNS TTL Checker

DNS TTL Checker is a focused network utility for administrators, developers, support teams and people troubleshooting an internet connection. Inspect DNS record values and their current cache lifetime in seconds.

Live results use a public lookup service. Only the address or hostname submitted for lookup is sent to that service.

Results describe public network information and should not be treated as proof of a person's identity or exact physical location.

Key features

  • Seven DNS record types
  • TTL in seconds
  • Record values alongside cache lifetime

How to use

  1. 1Enter a hostname or domain.
  2. 2Choose a DNS record type.
  3. 3Select Check TTL and review each returned cache lifetime.

Examples
