Querying a database as a domain name system resolver

Abstract

Querying a database by sending a plurality of arguments concatenated to a Domain Name System request and receiving a reply in the form of text or encoded as an IPv4 or an IPv6 address.

1 . A method for querying a database comprising the following steps:
 transmitting a dns request of class=IN;   concatenating a suffix comprising the host name serving the database to a plurality of query arguments to form a string formatted as a fully qualified domain name, a plurality of labels separated by dots and ending with a domain, a dot, a top level domain; and   transmitting dns queryname=the fully qualified domain name to a domain name system.   
     
     
         2 . The method of  claim 1  further comprising
 receiving at least one data value encoded within an Internet Protocol (IP) address format as a dns query response from the domain name system but does not actually represent an IP address. 
 
     
     
         3 . The method of  claim 2  further comprising
 sending a dns request selected from the following: type=A, type=AAAA, type=spf, type=CNAME, and type=TXT. 
 
     
     
         4 . The method of  claim 2  wherein the IP address is one of two to the 32 power unique values of the IPv4 system (four octets). 
     
     
         5 . The method of  claim 2  wherein the IP address is one of two to the 128 power unique values of the IPv6 system (eight groups of 4 hexadecimal digits). 
     
     
         6 . A method for querying a database comprising the following steps:
 sending a dns request of class=IN;   concatenating a suffix comprising the host name serving the database to a plurality of query arguments to form a string formatted as a fully qualified domain name, a plurality of labels separated by dots and ending with a domain, a dot, a top level domain;   sending dns queryname=the fully qualified domain name to a domain name system; and   receiving at least one data value encoded within an Internet Protocol (IP) address format as a dns query response from the domain name system but does not actually represent an IP address,   
       whereby the dns query response is cached in a distributed domain name system and served to a dns resolver. 
     
     
         7 . The method of  claim 6  wherein the IP address corresponds to a stored message which shall be displayed. 
     
     
         8 . The method of  claim 6  wherein the IP address represents that an email should be allowed without spam scanning. 
     
     
         9 . The method of  claim 6  wherein the IP address represents one of an action suggested, and a degree of additional handling.
