Bailiwick
The domain namespace for which a server is considered authoritative in a particular delegation context. Resolvers use bailiwick rules to decide which additional data, especially glue, can be safely cached.
Read definitionBase domain
An informal term that may mean the registrable domain, organizational domain, or zone apex depending on context. Because it is ambiguous, documentation should state the intended meaning.
Read definitionBCP
Best Current Practice, an IETF publication category for recommended operational or procedural guidance. A BCP can consist of one or more RFCs.
Read definitionBIND
Berkeley Internet Name Domain, a widely used open-source DNS server and tool suite maintained by ISC. Its configuration vocabulary influences many general DNS terms, even when another platform is used.
Read definitionBinding
The association between a client and configuration state, especially an assigned address or delegated prefix. A binding can include identity, lifetimes, options, and server ownership.
Read definitionBinding database
The persistent or replicated data store holding leases, reservations, identifiers, lifetimes, and states. Its consistency is critical during restart and failover.
Read definitionBlackhole DNS
A configuration that intentionally returns no useful result or directs selected names to a non-routable or controlled destination. The term can refer to policy blocking, sinkholing, or routing a DNS service address to discard traffic.
Read definitionBlocklist
A list of domains, addresses, clients, or indicators for which an action such as deny, redirect, log, or quarantine is applied. Modern documentation often uses blocklist instead of blacklist.
Read definitionBloxOne DDI
Infoblox cloud-managed DDI capabilities that provide DNS, DHCP, and IPAM services through BloxOne and NIOS-X service architecture. Product packaging and feature names evolve, so deployed documentation should be checked.
Read definitionBloxOne Threat Defense
An Infoblox DNS security platform that applies protective-DNS policy, threat intelligence, analytics, and ecosystem integrations. It is often abbreviated B1TD.
Read definitionBogon
An address or prefix that should not appear as legitimate Internet-routed source or destination space, such as unallocated, reserved, or improperly advertised space. Bogon lists change as registries allocate resources.
Read definitionBogus
A DNSSEC validation state indicating that the resolver expected a verifiable chain but validation failed. A validating resolver normally returns SERVFAIL rather than the unvalidated data unless policy says otherwise.
Read definitionBOOTP
The Bootstrap Protocol, a predecessor to DHCP used to provide startup configuration and boot information. DHCP preserves the BOOTP message format and extends it with leases and options.
Read definitionBootstrap server
A server that supplies initial network or boot configuration to a client. Depending on context, it may be a DHCP server, TFTP server, HTTP boot server, or provisioning controller.
Read definitionBroadcast
Delivery to all hosts on a local broadcast domain. DHCPv4 clients initially use broadcasts because they may not yet know their address, server, or default gateway.
Read definitionBroadcast address
The highest address in a traditional IPv4 subnet, used to reach all hosts on that subnet. Modern point-to-point /31 networks are an important exception.
Read definitionBulk leasequery
A mechanism for retrieving a large set of DHCP lease or binding data efficiently, often after a collector restarts. It is used by relay agents, access devices, accounting systems, and IPAM integrations.
Read definitionBYOIP
Bring Your Own IP, a cloud service capability that lets an organization advertise or use address space it owns through a cloud provider. It requires registry authorization, routing controls, and careful IPAM ownership tracking.
