Gateway Administration Guide

Product name
BlueCat Gateway

The following concepts can be useful in understanding BlueCat Gateway features and functionality.

Tip: For a more detailed glossary with additional terms about DNS in general, see BlueCat's DNS glossary on the BlueCat website.

Address Manager (BlueCat Address Manager)

BlueCat’s IPAM solution that brings all IP address, DNS, and DHCP information into a single management tool. Gateway connects to Address Manager, letting you build customized and automated BlueCat Address Manager solutions for your organization.

BDDS (BlueCat DNS, DHCP Server)

The DNS and DHCP servers that get their data from BAM and serve it to clients.

Crossover high availability (xHA)

A BlueCat feature that aims to ensure a certain level of operational performance or uptime for a system.


The integration of DNS, DHCP, and IPAM into one management solution.

DHCP (Dynamic Host Configuration Protocol)

The standard mechanism to dynamically assign IP addresses within a network.

DNS – Domain Name System

A hierarchical naming system that enables communication across devices in a network.

DNS record

Tells servers precisely how to respond to a DNS query.

DNS server / DNS name server

Contains IP addresses and their associated hostnames, and serves to resolve those names to IP addresses as requested.

DNS zone

A distinct, contiguous portion of the domain name space for which administrative responsibility has been delegated to a single manager.

Dynamic IP Address

An IP address that changes from time to time, unlike a static IP address.

Fully Qualified Domain Name (FQDN)

A domain name that specifies its exact location in the tree hierarchy of DNS.

High Availability (HA)

A feature that aims to ensure a certain level of operational performance or uptime for a system. This is typically accomplished by ensuring that a standby instance is always active and ready to take over operations should the main instance fail.

IPAM (IP address management)

A method for planning, tracking, and managing IP address space on a network.

IPv4 (Internet Protocol version 4)

The fourth version of Internet Protocol that uses 32-bit addresses to route most of today’s internet traffic; the global supply of IPv4 addresses is exhausted.

IPv6 (Internet Protocol version 6)

The most recent version of Internet Protocol, which uses 128-bit address space; there are 340 undecillion IPv6 addresses.

Lightweight Directory Access Protocol (LDAP)

An open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an IP network.


An API (application program interface) that uses HTTP/HTTPS requests to access and use data and functionality. A fully RESTful API conforms to a specific set of architectural constraints that make it simple, flexible, and easy to test (since you can typically enter a request directly into a web browser). REST stands for REpresentational State Transfer

As of v23.1, Gateway includes an updated RESTful API client ("REST v2") that allows direct access to the Address Manager RESTful v2 API, a fully RESTful API.

Simple Network Management Protocol (SNMP)

A protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior.

Simple Object Access Protocol (SOAP)

A messaging protocol specification for exchanging structured information in the implementation of web services in computer networks.

SSL (secure sockets layer)

Security technology for establishing an encrypted link between a server and a client.

Transport layer security (TLS)

A cryptographic protocol to provide communications security over a computer network.


A workflow is piece of functionality, such as generating reports, configuring security policies, or adding a user to a user group. In Gateway workflows, a UI is optional; workflows without a UI component are typically run by automated scripts or triggered by events.

Administrative workflows comprise core Gateway functionality and cannot be edited by users. Custom workflows are workflows created by users, or added as part of an adaptive application or plugin.


A logical location to organize workflows and their necessary data, including configurations, permissions, group settings, requirements, and other customizations. In practical terms, a workspace is typically a Docker volume or a folder on your local machine.
