TRANSCRIPT
Enum is a Domain Name
• Enum takes an E.164 telephone number and turns it into an Internet domain name.
+1 202-555-1234 = 4.3.2.1.5.5.5.2.0.2.1.e164.arpa
• The Domain Name System (DNS) is the infrastructure that supports addressing (i.e., routing) for the Internet.
• Why turn telephone numbers into domain names?– Devices traditionally addressed with telephone numbers are becoming
Internet-enabled, e.g., telephones, fax machines.
To understand Enum, one must first understand the DNS.
