Questions
How long do DNS changes take to show up?
Up to the record's TTL, shown in seconds in the results. Resolvers that cached the old answer keep it until the TTL runs out.
How do I do a reverse DNS lookup?
Choose PTR and enter an IP address. The tool converts it to the in-addr.arpa or ip6.arpa name for you.
