I have performed a dig on my domain name used on my site and I seem to be getting different results when I drop the "www." from the lookup. I am concerned this is causing me issues within my application, however i'm not sure if it's a red herring or not.
When I do this:
dig @22.214.171.124 www.php53.staging-crm.com
;; ANSWER SECTION: www.php53.staging-crm.com. 14400 IN A 165.160.xx.xx www.php53.staging-crm.com. 14400 IN A 165.160.xx.xx
Similarly, when I drop the "www.":
dig @126.96.36.199 php53.staging-crm.com
;; ANSWER SECTION: php53.staging-crm.com. 14400 IN A 80.75.xx.xx
(full IP addresses have been removed).
What would cause these to return different IP addresses?
