{: #known-limitations}
This section details some of the known limitations of {{site.data.keyword.dns_short}}. {: shortdesc}
- Resolvers cache permitted network details for a zone. The TTL for these cached details is typically 1 hour.
- In custom resolvers, disabling both custom resolver locations at the same time may be possible, but is not recommended when the custom resolver is enabled.
- {{site.data.keyword.dns_short}} custom resolver platform metrics do not track secondary zone usage. This means that DNS queries made to a configured custom resolver for a secondary zone will not be counted in the reported metrics.
