ABSTRACT:
Systems and methods of storing DNS data associated with a telephone number are presented. These systems and methods can reduce storage space needs, increase access speed and/or result in other benefits, in comparison with the prior art. In some embodiments, DNS data is indexed using a numerical representation of a telephone number rather than an alphanumeric representation. In some embodiments, DNS data associated with several different telephone numbers are grouped together within a single DNS data record and indexed using a secondary key. In some embodiments, DNS data is compressed.
