FAQ
A Record Lookup questions
What is an A record?
An A record maps a hostname to an IPv4 address.
Can a hostname have multiple A records?
Yes. Multiple A records are common for load balancing and redundancy.
Should I also check AAAA records?
Yes if the service supports IPv6 or you need a full view of published address records.
