What is E.164 Number Mapping (ENUM)? | DDI (Secure DNS, DHCP, IPAM) | Infoblox
Skip to content Home » Glossary » What is E.164 Number Mapping (ENUM)? What is E.164 Number Mapping (ENUM)? E.164 Number Mapping (ENUM) is a standard adopted by the Internet Engineering Task Force (IETF) that uses the Domain Name System (DNS) to map telephone numbers to web addresses or uniform resource locators (URL). The goal of the ENUM standard is to provide a single number to replace the multiple numbers and addresses for an individual’s home phone, business phone, fax, cell phone, and email.
