I created chat.ohfloat.com with the DNS manager. Even though remote systems can find this domain name, it is not found on my linode.

Actually, it is because the first nameserver in /etc/resolv.conf was not working forsome reason.

The "5515" here tells you the response is a cached one, and it will be refreshed by the DNS server you're using in 5515 seconds, ie. about 92 minutes at the time you made the query.

The "78771" in the other answer section means that it has a little less than 22 hours until the DNS cache is reloaded.
