note 19508 modified in function.checkdnsrr by vrana

Hi, Interesting thing I've discovered regarding checkdnsrr. When querying a domain's status using the command, always append a dot to the end of the domain you are querying. I.e. <?php checkdnsrr($domain.'.') ?> The dot is sometimes necessary if you are searching for a fully qualified domain which has the same name as a host on your local domain.. ie :- You want to search for "our.info" and you happen to have a node on your domain called : our.info.ourdomain.com If your DNS server is told to check 'ourdomain.com' before any other you will get a positive result when in fact our.info might not exist. For this reason adding the dot enforces the root. Of course the dot does not alter results that were OK anyway. Hope that helps some poor confused people :o) Alex. --was-- Hi, Interesting thing I've discovered regarding checkdnsrr.
