DNS Monitoring Across Networks

Monitor your DNS servers, resolvers and vendors.

Why is DNS Monitoring Important?

Without working DNS your network and applications are dark. Most organizations rely on external DNS registrars and hosts, but have little understanding of DNS server outages or visibility into performance issues.

ThousandEyes sheds light on the performance of your DNS infrastructure, from caching servers to external providers. We monitor the performance of DNS servers, resolvers and records in your network, those of your vendors and across the DNS hierarchy.

See DNS performance tests side-by-side with routing, path tracing and app availability data to help you solve DNS problems such as server performance, caching errors, record misconfigurations and cache poisoning.

With ThousandEyes, you can monitor on-premises, check DNS servers, hosted or third-party, to determine availability, and measure resolution time and record mappings. You can also trace the entire DNS hierarchy for a record, from top level domain servers to the authoritative server and understand if DNS infrastructure outside of your control is causing DNS errors because of an outage or performance degradation.

ThousandEyes can help you perform DNS troubleshooting by:
  • Understand the connectivity to authoritative servers with easy auto-discovery, routing, path tracing and availability metrics.
  • Measure the availability, responsiveness and record accuracy of your local DNS resolvers, across all office and data center locations.
  • Easily customize, configure and export DNS watch alerts on DNS availability, record mappings and DNSSEC.
  • Detect DNS cache poisoning in your network or in remote networks by alerting on record mappings.
  • Verify the DNSSEC keychain from the bottom up.
