DHCP IP reservation or Set a Static IP address for a device? ›

Static IP allocation ensures seamless IP allocation and management of these devices. For mobile devices that frequently move between networks, DHCP IP allocation is more convenient since it can automatically assign IP addresses regardless of the network.

Static IP addresses are configured manually, directly on the client. Reserved IP addresses are leased from the DHCP server, but the given client will always receive the same IP address. The DHCP service identifies the client by MAC address, as seen below.

Add a DHCP Reservation:

Select the option to add a new reservation or static IP entry. Enter the MAC address of the device. Assign a specific IP address that you want to reserve for the device. Make sure it's within the DHCP range of your router but outside the range of automatically assigned IPs.

Unlike with Dynamic Host Configuration Protocol (DHCP), which dynamically assigns IP addresses to devices, reserving an IP address guarantees that a specific device always receives the same IP address.

A static IP address is a fixed address assigned to a device on a network. Unlike DHCP, where the address can change each time a device connects to the network, a static IP remains consistent. This is typically configured manually and doesn't change unless altered by network administration.

A static IP address provides a device with a constant and unchanging network identification. It helps to ensure that devices can always access services like website and email server hosting and FTP. Convenient remote access.

Reservations provide a way to ensure that certain devices on the network always receive the same IP address, combining the flexibility of dynamic addressing with the predictability of static addressing for specific devices.

One of the main benefits of using static IP addresses is that they are easier to manage and troubleshoot. You can configure your devices with specific settings and preferences, and you do not have to worry about conflicts or errors caused by changing IP addresses.

On an IP network, each device connected to the Internet must be assigned a unique IP address. DHCP helps network administrators to monitor and assign IP addresses in a centralized manner. It can automatically assign a new IP address to a computer when it is moved to another location.

Can I assign static IP addresses and still use DHCP? ›

Yes, it can be done, however the IP range assigned to DHCP server should not contain the static IP otherwise it can be assigned twice and make a duplicate IP issue.

To configure a different Wi-Fi connection as Static, connect the device to that network and then configure the Static IP (IP, Gateway, etc.) through the console. Locate the device you'd like to configure in Devices & Groups.

There are several primary advantages of using DHCP reservations. One is the “static” IP address assignment is centrally managed and doesn't require you to document the allocation manually. Most routers provide a handy reservation table you can consult when you need to.

To make it easier to manage TCP/IP settings, we recommend using automated Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns Internet Protocol (IP) addresses to the computers on your network if your network supports it.

It is also recommended to use static IP addresses for devices within the network that are accessed by the Internet (as in the case of a web server) or when it is critical that a data connection is not interrupted.

Setting static IP addresses can help to avoid network conflicts which could cause certain devices to stop working correctly. However, in most installation scenarios, users will use a regular network and will not need to use a static IP.

Most users don't need static IP addresses. Static IP addresses normally matter more when external devices or websites need to remember your IP address. One example is VPN or other remote access solutions that trust (whitelists) certain IPs for security purposes.

A static IP address is the better option for enterprises that own websites and internet services. Dynamic IP addresses are better suited for home networks and personal internet use. Static IP addresses are particularly useful for enterprises that need to guarantee server and website uptime.
