Do cable modems provide DHCP?
By default, the cable modem router acts as a DHCP server. The cable modem router assigns IP, DNS server, and default gateway addresses to all computers connected to the LAN. You can use another device on your network as the DHCP server, or specify the network settings on all of your computers.
Is DHCP an ISP?
DHCP Protocol Via ISP Your ISP has a Dynamic Host Configuration Protocol server that assigns IPs by modem MAC addresses. When your modem comes online, it communicates to the network indicating it is looking for an IP address. The DHCP server listens to this communication and starts talking to the modem.
How do I enable DHCP on my modem?
This will usually be in the “Network Settings” section (or your router page’s equivalent). If you can’t find DHCP there, look for it in the “Advanced” settings, “Setup” settings, or “Local Network” settings. Enable DHCP. Click the Enable switch, checkbox, or button.
Should my router and modem have the same IP address?
A router may have the same private IP address as a modem, but these are not used to connect to the network directly. However, public IP addresses are assigned by the ISP and may never be the same. In the same way, each interface gets a unique IP address.
Which is faster PPPoE or DHCP?

Normally, you never want two routers both trying to provide DHCP and NAT services.
What does bridge mode on AirPort Extreme Mean?
Note: If your router mode is set to “Off” or “Bridge Mode,” that means another device on your network, such as an integrated modem and router from your ISP, is handling DHCP within your network and the Airport Extreme is simply passing the connection along via wireless and Ethernet.
