Abstract
This RFC describes the concepts and facilities of the Domain Name System (DNS), including the domain name space, resource records, name servers, and resolvers. It introduces the hierarchical, distributed database architecture that allows domain names to be resolved globally without requiring any single central authority to maintain the entire namespace.
Why This RFC Matters
RFC 1034, together with RFC 1035, forms the foundational specification for the Domain Name System, one of the most critical infrastructure components of the modern Internet. The hierarchical delegation model it defines has scaled remarkably well from thousands to hundreds of millions of domain names. Without DNS, users would be required to remember numeric IP addresses for every service they access. The concepts defined in this RFC — zones, delegation, recursive resolution — remain the basis of DNS operation today.
