said by T1 Rocky :When does it go into affect and what are the repercussions? The effect is simple. If I have an application that needs to know if a given FQDN (Fully Qualified Domain Name) is valid, this false reply will make ALL FQDNs look valid not just those that ARE valid. Such an application is SMTP (Mail) Servers which check Email Addresses to see if the Domain Name in the address exists. Use of this false existence reply would cripple the SMTP checks. |
