PPPoE vs DHCP may sound like two irrelevant items since the application of each is not the same: DHCP is a protocol for obtaining IP addresses while PPPoE is a common method of connecting to an ISP. But the debate over PPPoE vs DHCP differences has been around for a long time and thus causes a lot of confusions. So in this article, we will have PPPoE vs DHCP explained and walk you through how they differ from each other.
PPPoE vs DHCP: DHCP Wiki
DHCP, or Dynamic Host Configuration Protocol, is a standardized client/server network protocol that dynamically assigns IP addresses and other related configuration information to network devices. It is known that each device from a TCP/IP network should have a unique IP address to access the network. 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. Usually, a DHCP architecture is made up of DHCP clients, DHCP servers and DHCP relay agents.
DHCP works to offer an automated way to distribute and update IP addresses and other configuration information on a network. A DHCP server provides this information to a DHCP client through the exchange of a series of messages. DHCP enables network users to travel anywhere on the network and automatically receive an IP address when they reconnecting. 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. DHCP also helps to conserve limited IP address space.
PPPoE vs DHCP: What Is PPPoE?
PPPoE vs DHCP: How They Differ?
DHCP is a way for a network to allocate unique IP addresses to the devices (i.e. computers, smartphones Gigabit Ethernet switch and etc.) within a network so that traffic can be delivered back-n-forth without confusion. PPPoE is a way to encapsulate network traffic, based on credentialed access (i.e. username/password). 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. So using DHCP to connect to an ISP eliminates the problems that are associated with PPPOE. 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.
The difference between PPPoE vs DHCP can be summarized as follows:
- DHCP is a protocol for obtaining IP addresses while PPPoE is a common method of connecting to an ISP
- DHCP is very popular and is widely used while PPPOE is slowly falling out of favor
- You would need to have a username and password with PPPOE while the configuration of DHCP is automatic
So we’ve explored the definition of each term and major PPPoE vs DHCP differences. It is thus to conclude that there is no “one is better than the other”- PPPoE and DHCP serve two entirely different purposes without overlap. Hope it would help to clear out your confusion.
