View the Start of Authority (SOA) record for pinterest.com. See zone authority, timing parameters, and serial number.
SOA (Start of Authority) records are the cornerstone of every DNS zone. The SOA record is always the first record in a zone file and defines critical metadata about the zone: which nameserver is the primary authority, who is responsible for the zone (hostmaster), and how secondary nameservers should handle zone transfers and caching. The timing parameters — refresh, retry, expire, and minimum TTL — control the synchronization behavior between primary and secondary DNS servers, ensuring that DNS data stays consistent and up to date across the internet.
The SOA record for pinterest.com determines how its DNS zone is managed and replicated. If the refresh interval is too long, DNS changes to pinterest.com will propagate slowly. If the expire value is too short, secondary nameservers may stop serving pinterest.comduring a primary server outage. The serial number tracks zone versions — secondary servers use it to detect updates. A misconfigured SOA record can lead to stale DNS data, failed zone transfers, or inconsistent resolution of pinterest.com across different DNS resolvers worldwide.
The SOA (Start of Authority) record for pinterest.com contains critical zone information including the primary nameserver, hostmaster email, serial number, and timing parameters that control how DNS data is refreshed and cached. Check the live results above to see the current SOA record.
The serial number in pinterest.com's SOA record is a version identifier for the DNS zone. Each time the zone is updated, the serial is incremented. Secondary nameservers compare this value to determine whether they need to request a zone transfer. A common format is YYYYMMDDNN (date + revision number).
The SOA record is the first record in every DNS zone and defines how the zone operates. It specifies the primary nameserver, the responsible party (hostmaster), and timing parameters like refresh, retry, expire, and minimum TTL. These values control how often secondary servers sync with the primary, how long they wait before retrying, when they stop serving stale data, and the default negative cache duration.
