R
Random Forest
Grouping the output of multiple decision trees together into a final result. This should be used when a single decision tree does not provide accurate results for all scenarios. [ Type: Terminology ]
RBL
Realtime Blackhole List. [ Type: Data ]
Reclaim Accounts

Red Team - Blue Team
An exercise in which a system's security is tested by security experts. Red team is in charge of attacking and gaining access/control of an objective while the blue team is responsible for defending it. This exercise is meant to test the system and reveal vulnerabilites and measure the readiness of the security team responsible for defending it. [ Type: Terminology ]
Reserved domains
Domain has been reserved via the dropcatcher service. Incase the user decides not to renew the domain, another person can take it. [ Type: Terminology ]
Reverse WHOIS
The Reverse whois will do a reverse IP lookup. If an IP address is typed, it will attempt to locate a DNS PTR record for that IP address. Reverse WHOIS provides clients with ownership and relationship information for entities on the Internet, including domain names, IP addresses, registrars, registries and ISPs. [ Type: Analysis ]
Root Zone
Root Zone refers to the highest level of the Domain Name System (DNS) structure. It contains the names and the numeric IP addresses for all the top level domain names such as the gTLDs (.com, .net, .org, .jobs), and all the country code top level domains (ccTLDs), for example (.us, .uk .ph), including the entire list of all the root servers. The DNS root zone contains only 280 delegations of generic, country code and internationalized top level domain names (TLD)s and its size is more or less 80,000 bytes. It also changes slowly and absorbs only one minor change per TLD every year. The National Telecommunications Information Administration (NTIA), ICANN, Verisign and the Root Server Operators play significant roles in the management and process of the root zone. NTIA is an agency under the United States Department of Commerce, which represents the federal government in a contract entered in with ICANN and Verisign, which grants the organizations separate functions in managing the performance of the root zone. NTIA is responsible in reviewing and approving whatever changes that need to be implemented within the root zone. ICANN is the operator of the Internet Assigned Numbers Authority (IANA), which is responsible for the day-to-day management of the DNS root zone. IANA assigns the operators of the top level domain and ensures the maintenance and the administrative details of the TLDs. It is also responsible for the coordination of the Internet Protocol (IP) and Autonomous System Numbers (ASN) to the Regional Internet Registries (RIR). Verisign, and formerly Network Solutions, serves as the root zone administrator under a cooperative agreement entered with the United States government; this has been in effect since 1998. The Root Server Operators' primary role is to make sure that the operations of the root zone is always accurate, available, reliable and secure. There are thirteen Root Server Operators in the database of the root zone, which include: A - Verisign Global Registry Services B - Information Sciences Institute C - Cogent Communications D - University of Maryland E - NASA Ames Research Center F - Internet Systems Consortium, Inc. G - U.S. DOD Network Information Center H - U.S. Army Research Lab I - Autonomica/NORDUnet K - RIPE NCC L - ICANN M - WIDE Project. [ Type: Terminology ]
