Welcome to DNS Check! This page provides a brief introduction, then points you towards the documentation that's most relevant to your goals.
DNS Check is a tool that compares the DNS records that you indicate should exist to what is returned by name servers. If the DNS records match, then the check passes. Otherwise, the check fails, and DNS Check notifies you, providing information on why the failure occurred.
Use Cases
DNS Check has three typical uses:
- Monitor DNS Records and Name Servers - DNS Check notifies you if a record starts passing or failing.
- Share DNS Records - Share a list of DNS records that you'd like to be created or updated. DNS Check enables both you and the person you're sharing the records with to easily see and get notified when the updates are posted.
- Troubleshoot DNS Records and Name Servers - If something's broken, and you suspect DNS is at fault, tell DNS Check what DNS records should be returned by which name servers. DNS Check quickly identifies any DNS-related issues and locates their source.
If any of the descriptions match what you're trying to accomplish, then viewing that subject's document is the recommended next step. Otherwise, continue to the next section.
DNS Record Groups
DNS Check groups related DNS records into DNS record groups. DNS record groups can have a 1:1 correlation with zone files, but this is not a requirement. For example, if you prefer to place all DNS records that relate to a specific service into a single DNS record group, then you're welcome to do so. You're also welcome to place all the DNS records that you're checking into a single DNS record group if you'd like.
To start working with DNS record groups, click the DNS Checks link in the top navigation bar.
Here's an example DNS record group, which has both passing and failing DNS records. DNS records that pass their checks appear in green, and those that fail appear in red.
See the DNS Record Groups document for a more in-depth discussion of this topic.
Notifications
If you want to be notified each time a DNS record starts passing or failing, then you have many notification options available, including receiving an email, being paged, and receiving a chat notification. See our Notification Settings documentation for more information.
Account Types
DNS Check accounts get created as "Basic" accounts, which are free, but have a couple of limitations in place:
- Basic accounts are limited to checking 10 DNS records at a time
- Basic accounts always query DNS Check's name servers. There is no option to query custom name servers.
You can lift both these restrictions at any time by upgrading to a Professional or Enterprise account. A more detailed comparison of the available plans is on the Features page.
A Professional account can be downgraded to a Basic account at any time from your Profile page.
