What happens if you have two DHCP servers on the same network?

If you are considering multiple DHCP servers, remember that multiple DHCP servers cannot share any of the same addresses. If you use more than one DHCP server in your network, each server must be configured with their own unique IP address ranges.

Should I use DHCP on my access point?

If you want a bit of extra protection for the users on your network, you should set up your Access Points as basic routers. Provides IP addresses – Using DHCP, the Access Point will provide an IP address to devices that connect, in a private range.

What is the point of DHCP reservations?

DHCP Servers support something called a “DHCP Reservation”, which essentially allows you to provide a pre-set IP address to a specific client based on it’s physical MAC address. This means that the device will always get the same IP address and it will never change (whereas they typically do on occasion).

What is DHCP reservation used for?

A DHCP reservation is a permanent IP address assignment. It is a specific IP address within aDHCP scope that is permanently reserved for leased use to a specific DHCP client. Users can configure a DHCP reservation in their DHCP server when they need to reserve a permanent IP address assignment.

Should I disable DHCP on second router?

If you connect a second router to extend the subnet from the primary (ISP connected) router, then you must disable DHCP in the second router if any devices are configured to to get their addresses automatically.

What happens if DHCP server is down?

If a DHCP server fails or goes offline, network communications can quickly break down. Without DHCP, you’d need to go to each computer and manually assign it an IP address, subnet mask, default gateway and other network settings.

What is the difference between a static and a DHCP reservation?

Just to state the obvious: A static IP address is an IP address that’s manually set on a NIC (Network Interface Card). A DHCP Reservation is a pre-set IP that’s provided by a DHCP Server, and given to a NIC when a NIC calls out to a DHCP server for an IP address.

What if I can’t use DHCP reservations on my router?

If, for some reason, you can’t use DHCP reservations, you can set up a static IP on each of your computers instead, but this is our preferred method. Many routers support DHCP reservations out of the box, but if they don’t, you can always install the DD-WRT firmware, which adds the support to many more routers.

Is DHCP plug and play or static?

So in most cases, when using DHCP, it is Plug and Play. DHCP reservations virtually guarantee the same IP address is provisioned on a device. In this way, reservations behave very much like Static IPs.

Is it possible to mix static and DHCP IP addresses?

Mixing Static IP addresses and those assigned via DHCP is not only possible but can be beneficial.
