Frequently Asked Questions
What is an A record?
An A record maps a domain name to an IPv4 address (and AAAA to IPv6). This tool queries it via different resolvers so you can spot differences.
Why does the result differ by resolver?
Due to caching or incomplete propagation, different resolvers may temporarily return different values; this is useful for checking propagation.
