A DNS zone is any distinct, contiguous portion of the domain name space in the Domain Name System (DNS) for which administrative responsibility has been delegated to a single manager. The domain name space of the Internet is organized into a hierarchical layout of subdomains below the DNS root domain. The individual domains of this tree may serve as delegation points for administrative authority and management. However, usually it is furthermore desirable to implement fine-grained boundaries of delegation, so that multiple sub-levels of a domain may be managed independently. Therefore, the domain name space is partitioned into areas (zones) for this purpose. A zone starts at a domain and extends downward in the tree to the leaf nodes or to the top-level of subdomains where other zones start.
Hash-based electronic signatures for data sets such as dnssec
Techniques for electronically signing DNS records stored in a zone file for an internet DNS zone are presented. The techniques include electronically accessing a plurality of DNS resource records of a DNS zone stored on one or more DNS servers of a distributed DNS database; generating a plurality of leaf nodes from the plurality of DNS resource records; constructing a recursive hash tree from the plurality of leaf nodes, where the recursive hash tree includes a plurality of nodes including a root node and the plurality of leaf nodes, where each node of the plurality of nodes includes either a leaf node or a hash of data including child nodes; storing the root node in a DNS key resource record for a zone signing key for the zone; and publishing, in a DNS resource record signature resource record, validation data including path data from the recursive hash tree.

System and method for electronic certificate revocation
ActiveUS7120793B2Digital data processing detailsUser identity/authority verificationClient-sideDNS zone
A system and method of verifying whether a certificate has been revoked by providing a DNS responder containing a certificate revocation list (CRL), parsing the CRL into DNS zones, and distributing this information to the respective primary DNS responders based upon DNS zones. Information about a specific certificate is gathered by querying a DNS responder for certificate validation information, receiving such information, and reporting the results of the queries to a client software application so that the user of the system can be informed as to whether the certificate has been revoked or not.

Opt-in process and nameserver system for IETF DNSSEC
InactiveUS20080260160A1Facilitating DNSSEC deploymentDecreases comprehensivenessSpecial service provision for substationPublic key for secure communicationComputer networkName server
The process of signing and then publishing a DNS zone according to the IETF DNSSEC protocols is improved by the present invention, in order to facilitate the DNSSEC deployment until most of the DNS zones are signed. The prior art situation is that a second-level domain, e.g. example.com, often faces an unwanted status of “DNSSEC island of security,” and a challenging task of “trust anchor key” out-of-band distribution. The invention somehow fixes such broken DNSSEC chains of trust, e.g. it fills the gap between a DNSSEC island of security and its signed grandparent or ancestor. The invention is deemed useful for the introduction of DNS root nameservice substitution for DNSSEC support purposes, and allows opt-in while NSEC3 opt-out is awaiting deployment in large TLDs.

Method for administering a top-level domain
A method for administering a top-level domain by analyzing domain name registrations for requests for suspicious or malicious domain names. A request to register a domain name is received. The requested domain name's information may be stored in a registry database. The requested domain name may also be conditionally stored in the domain name system (DNS) zone. The requested domain name is compared to a list of botnet domain names stored in a watch list database. If the requested domain name corresponds to one of the botnet domain names, the requested domain name is prevented from being added to the DNS zone or is removed from the DNS zone, if it has already been stored there. The information regarding the requested domain name is stored in the registry database, even if the domain name does not ultimately stay in the DNS zone.

Establishing caches that provide dynamic, authoritative DNS responses
InactiveUS20160028847A1Well formedDigital computer detailsTransmissionComputer networkDomain Name System
Embodiments are directed to establishing caches that provide authoritative domain name system (DNS) answers to DNS requests. In one scenario, a computer system establishes a cache that stores authoritative DNS answers to DNS queries. The cache corresponds to a specified DNS zone that includes authoritative DNS answers for a subset of DNS queries. The cache is configured to store the authoritative DNS answers for at least a specified period of time during which the authoritative DNS answers are updatable. The cache then receives an update indicating that at least one cached DNS answer is out-of-date and the computer system purges the out-of-date DNS answer from the cache, ensuring that the cache continually provides authoritative DNS answers for DNS queries assigned to the specified DNS zone.
