DNS Lookup
Query the live DNS records for any domain. See A, AAAA, MX, TXT, NS, CNAME and SOA records with their TTLs.
Monitor the domains and networks you run.
ISPbox gives you network monitoring, automatic incidents and a public status page out of the box. Free to start.
DNS record types explained
A DNS lookup asks the domain's authoritative name servers which records it publishes. A and AAAA map a name to an IPv4 or IPv6 address, MX points mail to the right servers, NS lists the name servers, CNAME aliases one name to another, TXT holds verification and SPF/DKIM data, and SOA carries the zone's serial and refresh settings.
About TTL
Each record has a Time To Live in seconds that tells resolvers how long to cache it. Lower TTLs propagate changes faster but add lookup load; higher TTLs are cached longer. If you just changed a record and still see the old value, its TTL has not expired yet.
