Getting Started with DNS Check What DNS Check does, and which page to read next for what you're trying to do.
Example DNS Check A public record group holding both passing and failing records, viewable without an account.
Monitor DNS Records Create a record group, add the records to watch, and set how often they're checked.

DNS Record Groups Ways to organize monitored records: by zone, by service, or by customer.
DNS Record Types Every record type DNS Check monitors, and what each one is for.
Zone Files Import records from a zone file, and export a record group back out to one.
Wildcard DNS Records Monitor a wildcard name, or accept any answer by monitoring a wildcard value.
Load Balancer Records (Professional or Enterprise plans) Monitor one record that holds a set of acceptable values, as addresses or CIDR ranges.
Exclusive DNS Record Matching Fail a check when a name server returns extra or duplicate records beside the one you entered.
Inverted DNS Checks (Professional or Enterprise plans) Pass a check while a record is absent, to catch an unwanted record appearing.

Notification Settings Which state changes send a notification, and whether it arrives by email, chat, or pager.

Webhooks (Enterprise plans) Post a signed notification to your own HTTPS endpoint when a DNS record changes state.
