The Dynamic Host Configuration Protocol (DHCP) server plays a central role in managing IP address assignments and network configuration in a computer network. Its primary functions are summarized in the Table below.
Feature |
Description |
---|---|
IP Address Assignment | The DHCP server allocates IP addresses dynamically to devices on the network as they connect. This ensures that devices have unique and valid IP addresses, reducing the likelihood of IP address conflicts. |
Network Configuration | DHCP provides not only IP addresses but also essential network configuration parameters to connected devices, including subnet masks, default gateways, and DNS (Domain Name System) server addresses. This simplifies network configuration for users and administrators. |
Lease Management | DHCP assigns IP addresses with lease durations, specifying how long a device can use the assigned address. When the lease expires, the device must renew the lease with the DHCP server. Lease management helps optimize IP address utilization and allows for efficient resource allocation. |
Centralized Control | DHCP offers centralized control over IP address assignments and network parameters. This is critical for maintaining consistent network configurations, managing IP resources, and ensuring network security and compliance. |
Scalability | DHCP is highly scalable, making it suitable for networks of all sizes, from small local networks to large enterprise environments. It adapts to the network's growth and dynamically manages IP address assignments. |
IP Address Reservation | DHCP servers allow administrators to reserve specific IP addresses for particular devices, ensuring that critical resources receive consistent IP addressing. |
Monitoring and Logging | DHCP servers often provide monitoring and logging capabilities that track IP address assignments and troubleshoot issues. This helps network administrators maintain visibility and control over the network. |
Redundancy and Failover | When you deploy Exium's Cyber gateway in High Avaialbility (HA) mode, DHCP server is also replicated, ensuring that DHCP services remain available even in the event of a failure. |
As an integral part of Exium's Cyber Gateway (CGW), the DHCP server automates and streamlines the process of IP address assignment and network configuration, simplifying network management, optimizing resource allocation, and enhancing network efficiency.
To configure DHCP server for a new Cyber Gateway deployment, follow the steps below.
DHCP static leases needs to be configured in CyberGateway local admin console. Please follow instructions in Effortless Cyber Gateway Management for Gateway Control and credentials for DNS security.
Once you re in Gateway Console, Select DNS security from Gateway Console
Login with Credentials.
Go to Settings→ DHCP Settings
Scroll down and go to DHCP leases. Click on + action to make lease static
Once it is added, you will see entry in DHCP static leases. You can also click on “Add static Lease” ( see picture) and add static lease entry manually.
