DHCP vs. November 16, People often talk about the home controller being the "brains" of a smart home installation. Extending that metaphor a little further, you might consider your home network as the "nervous system" of your home automation setup.

Your home network allows all of your various devices to receive instructions from the controller, and also to provide status updates and other information about what's going on in the system. In a Control4 system, most network components need an IP address. Items on the Zigbee network, like switches and dimmers, thermostats and door locks, have their own network. Media players, touch screens, network-enabled televisions, networked receivers, speaker points and other connected devices all need to be connected to the network either via Ethernet or a wireless connection.

This is all done using IP Internet Protocol addressing.

Static IP Addressing With static IP addressing, addresses are assigned manually, and have to be provisioned carefully so that each device has its own address—with no overlap. When you connect a new device, you would have to select the "manual" configuration option and enter in the IP address, the subnet mask, the default gateway and the DNS server s. If you understood any of what I just said, you probably have the skills and knowledge necessary to manage static IP addresses on a home network.

When DHCP is enabled, a new device connected to the network asks the DHCP server for an address, and the server assigns one from its pool of unused locations. The server itself tracks which addresses are used and which addresses are available, and keeps a record of which addresses have been assigned to the various devices. This ensures that addresses don't conflict with each other.

However, it also means that, if a device goes offline, when it reconnects it may not have the same IP address it had before. Since the default DHCP address range is between andyou'll want to avoid all of the addresses between That leaves the ranges from and from wide open, which is usually plenty for most home networks. So Which Is Better? DCHP provides true "plug and play" networking, but it can come at a cost. There is less control, so you can't count on a particular device having a particular address if you have a networking challenge that requires this.

This would make it possible to hijack the network for nefarious purposes. Also, because DHCP servers make it so easy to add new clients to the network, DHCP also makes it possible to join a network without explicit permission. This issue can be prevented by forcing a DHCP network to require authentication when adding a new device, but that kind of defeats the purpose of DHCP in the first place.

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.

On the other hand, DHCP provides network admins quicker and more reliable IP address configuration — it mitigates configuration errors caused by manual IP address configuration. This allows the modem to be a part of the network that multiple users can utilize instead of being connected directly to the computer. The PPP protocol information is encapsulated within an Ethernet frame. More recent modems now incorporate the PPPoE dialer into them.

You can simply set your username and password once and your modem automatically connects to the internet whenever you turn it on. PPPoE is a way to encapsulate network traffic, based on credentialed access i. PPPoE needs to be configured correctly before a user can actually connect to the internet, however, modems that use DHCP does not need to be configured and is basically plug and play.

Just like with computers on a network, you do not need to configure your computer beforehand. You simply leave everything on automatic and leave the configuration to the ISP servers.

What type of internet connection is best? PPPoE, Static IP, DHCP, PPTP, L2TP, or Telstra Cable?

In the IP protocol, each device on a network has a unique identifier that is called IP address.

The easiest method of achieving this was configuring a fixed IP address or static IP address. Since there are limitations to static IP, some administrators seek to use dynamic IP instead. A static IP address is an address that is permanently assigned to your network devices by your ISP, and does not change even if your device reboots.

In static IP addressing, each device on the network has its own address with no overlap and you'll have to configure the static IP addresses manually. When new devices are connected to a network, you would have to select the "manual" configuration option and input the IP address, the subnet mask, the default gateway and the DNS server.

A typical example of using static IP address is web server.

Then type "ping www. The four-byte number If it is a static IP, you would be able to connect Google at any time by using this static IP address in the web browser if you want to visit Google. What is in contrast with the static IP address is the dynamic IP address.

Static vs dynamic IP topic is hotly debated among many IT technicians. Dynamic IP address is an address that keeps on changing.

DHCP is a way of dynamically and automatically assigning IP addresses to network devices on a physical network. 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 switcheswhich support dynamic binding by users' definition, are commonly used to allocate IP addresses for each device that is connected together.

Static Vs Dynamic IP Address

You can easily find their advantages and disadvantages from the following table. Having a static IP and guessing which IP address is available is really bothersome and time-consuming, especially for those who are not familiar with the process. However, static IP is still in demand and useful if you host a website from home, have a file server in your network, use networked printers, or if you use a remote access program.Essentially, both of them are a process of acquiring IP.

It combines the PPP that owns the function of authentication and encryption, and the Ethernet protocol that can support multiple users in a LAN. Figure 1. PPPoE working process includes two main phases:.

Difference Between DHCP and Static IP

And the hosts locate multiple PPPoE servers, and then allow the user to choose one. Session Phase—When the discovery phase completes successfully, both the host and the selected server have information about their PPP connection over the Ethernet.

Therefore, a session is established between an individual user and the remote site, which can be monitored. Meanwhile, the user billing is produced and recorded by PPPoE. So without DHCP configuration, network admins have to configure IP addresses manually if they want to add new computers or move computers from one subnet to another.

Figure 2. DHCP works to offer an automated way to distribute and update IP addresses and other configuration information on a network.

DHCP enables network users to travel anywhere on the network and automatically receive an IP address when they reconnect.

On the other hand, DHCP provides network admins a quicker and more reliable way to configure IP address — it mitigates configuration errors caused by manual IP address configuration. PPPoE is a way to encapsulate network traffic, based on credentialed access i. Just like computers on a network, you do not need to configure your computer beforehand. You simply leave everything automatic and leave the configuration to the ISP servers. Only when your account password is correct, will it assign a valid IP to you.

Since PPPoE enables a large number of host to form a network unit and control, bill each host, it is widely used in community, buildings, and campus. Using PPPoE, you have to configure a username and password first, which will make authentication next time you turn on the network to acquire an IP.DHCP stands for Dynamic Host Configuration Protocol and is commonly used in networks to automatically provide IP addresses to client computers so that they can communicate with other elements on the network.

This is an Ethernet encapsulation of the Point to Point Protocol that is commonly used with dial-up connections. This allows the modem to be a part of the network that multiple users can utilize instead of being connected directly to the computer.

DHCP is very popular as a great majority of networks use it to provide seamless connections to computers that are moved very often. Unlike PPPOE, which needs to be configured correctly before a user can actually connect to the internet, modems that use DHCP does not need to be configured and is basically plug and play.

In the past, this is done just like a traditional dial-up connection; with a dialer on your desktop. You can simply set your username and password once and your modem automatically connects to the internet whenever you turn it on.

Problems can occur when you lose or forget your username and password and the only possible solution would be to call up your ISP and ask for it again.

Terminator programs, bought two diff. You still need to know if the right person is using the bandwidth right? No need to check whether the right person is getting the bandwidth — as the days of dialup are over. DHCP Option By combination of the circuit id and remote id, the ISP can know form where is the DHCP request originating and hence can allocate resources to the customer accordingly.
