There could be many reasons to assign a static IP over DHCP, but a few of the key ones off the top of my head are: Routing - if traffic needs to go to a specific location, or take a specific path, then having DHCP assigning addresses dynamically is a massive no-no. The traffic could end up anywhere, and since you have no control of what gets assigned where, you have no way of knowing who got what when those leases expire.

Firewall rules - If you have a specific application i. Skype that needs to run on a specific device, but not the rest of the network, you need to ensure that the application is always going to be allowed access, or it'll be blocked. Assigning a static IP would mean that and only that device will be able to make the connection to the outside world.

Stability - since some programs require IP addresses rather than FQDN to make connections, ensuring that the IP address doesn't change can mean saving yourself hours of endless phone calls and frustration when it all implodes. Tracking it down to a wrongly assigned DHCP IP can take a long time if you don't know you're looking for it, so why give yourself the hastle in the first place? Also, might want to make sure you only post one thread not three next time - it'll save you some hastle tracking responses!

It provides an automated way to distribute and update IP addresses and other configuration information over a network. Proper IP addressing is essential for establishing communications among devices on a network. This part will discuss it. Static IP addresses allow network devices to retain the same IP address all the time, A network administrator must keep track of each statically assigned device to avoid using that IP address again.

DHCP is advantageous for network administrators because it removes the repetitive task of assigning multiple IP addresses to each device on the network. It might only take a minute but when you are configuring hundreds of network devices, it really gets annoying. Wireless access points also utilize DHCP so that administrators would not need to configure their devices by themselves. For wireless access points, PoE network switches , which support dynamic binding by users' definition, are commonly used to allocate IP addresses for each device that is connected together.

You can easily find their advantages and disadvantages from the following table. DHCP is especially dangerous when combined with an unprotected wireless network. You wouldn't think this would happen very often, but homeowners who don't understand the risks do this all the time.

This makes it possible for someone to sit with a laptop in a car on the street and gain access to every network resource: every computer, every network drive, and every tablet or phone connected to the LAN. It's like leaving your doors and windows open while at the same time leaving a welcome mat out for data and identity thieves.

For most home networks, fully dynamic or mixed addressing configurations are just fine. As long as all wireless networks are locked down and no "bad guys" can gain physical access to the network, DHCP is a good option for easy home networking. But if you are truly serious about network security—if you have sensitive data residing on your network or just want to make data or identity theft much less likely—you're probably better off sticking with disabling DHCP and maintaining full manual control of your home network.
