How to query and understand domain name DNS records
Enter the domain name and select the record type to query the authoritative public resolution results. Different records undertake different responsibilities such as website access, email delivery, domain name verification and security policies.A and AAAA
A record points to the IPv4 address, and the AAAA record points to the IPv6 address; the same domain name can have multiple records at the same time.
MX, NS and TXT
MX is used for mail routing, NS indicates authoritative DNS, TXT is often used for domain name ownership, SPF, DKIM and other authentication.
TTL and cache
TTL represents the length of recursive DNS cacheable records. After modification and parsing, the effective speed of each place will be affected by the old cache.
DNS record query Frequently asked questions
Why are the records seen locally different from the query results?
The local network may still use cache, or may return different results due to split line resolution, geoscheduling, or DNS contamination.
What do I need to enter for PTR reverse query?
The PTR query should enter the public IP address to find the reverse domain name of the IP configuration; not all IPs have a PTR set.
