What is DNS and IPAM?

Domain name system (DNS), dynamic host configuration protocol (DHCP), and IP address management are collectively referred to as DDI. The acronym DDI stands for DNS-DHCP-IPAM in networking. The link between hostnames and IP addresses is ensured by DNS. Almost all apps and services can be accessed using access routing, which maintains the flow of network traffic and HTTP web traffic.

For nodes connecting to the network, DHCP assigns dynamic IP addresses and automatically inherits configuration capabilities from the address plan tree. By making it possible for effective management of IP addresses across the network, IPAM supports several essential technologies. They come together to form DDI.

What is IPAM?

Organizations can manage a large number of IP addresses effectively and automatically with the help of IP Address Management (IPAM). The number of linked devices on today's networks, many of which are portable, is surging, and these devices all need temporary IP addresses.

Each device must be given a distinct IP address within the proper subnet, and any mistakes could cause crucial assets to go down.

In the past, IP address administration was carried out manually and recorded using spreadsheets. This was time-consuming, prone to mistakes, and plainly unscalable. Today, it is accepted that any mid-to-large enterprise network that dynamically allocates IP addresses to more than 240 devices or users must employ an automated IPAM system.

DNS, DHCP, and IPAM (DDI)

Dynamic Host Configuration Protocol (DHCP)

A DHCP server automatically allocates IP addresses to network resources while ensuring that each IP address is distinct and using the proper subnet mask. Many routers and network equipment come with built-in DHCP servers. They are frequently provided in conjunction with IPAM systems.

Modern IPAM systems are frequently provided alongside DHCP and DNS. This is referred to as a DDI solution (DDI stands for DNS, DHCP, and IPAM), which includes and pre-integrates all three technologies. By controlling network addresses from a single location, DDI systems relieve administrators of the significant task of setting up and configuring DHCP and DNS infrastructure.

The most popular way to purchase DDI is as a network appliance, which can be installed throughout the business network in various locations and take over all network addressing duties. Additionally, there are software-based options.

Domain Name System (DNS)

The core Internet addressing method, which is also widely used in business networks, assigns human-readable web addresses and converts them into machine-readable IP addresses. To ensure that web browsers and devices on the network can find and communicate with one another, large corporate networks run a network of authoritative name servers and recursive DNS servers.
