we have an PTR record problem. When we query "ege.edu.tr" in dnsreport.com it seems everything is ok. When we query virusguard.ege.edu.tr result is 155.223.64.33 and query 155.223.64.33 and result is virusguard.ege.edu.tr so everything seems work. But when we query from outside servers, they cant find PTR record for 155.223.64.33. Thanks for your help
