DHCP Server Question

[TheLyppardMan]

I'm only asking this question out of curiousity, but it should be an easy one for experts to answer.

The question is, if I were to disable the DHCP server, would those devices to which I have assigned an manual IP still function normally, or would all access to the internet, local network and the router itself be terminated because nothing would have an IP address from that point forward? If the answer is yes, then I assume that would mean that the only way to access the router would be to do a factory reset.

If you assign a valid manual IP address to clients, before or after disabling the DHCP Server, they will have access to local clients and the internet.
Set the clients Default Gateway and DNS Server to the routers IP address, especially so if AB-Solution is installed.

It depends what you mean by "assigned a manual IP".

If you mean a "static IP" which you set manually on the client's network interface then @thelonelycoder 's answer would apply.

If you mean the router's "Manually Assigned IP around the DHCP list" settings, then you would have very limited network connectivity because this "manual" assignment works through DHCP (which you've turned off). So your client wouldn't get its normal IPv4 address. But it would probably still have a link-local address which could give you some basic network connectivity. But realistically in that situation you would setup a static IP address on the client to give you back proper network access.

OK, thanks guys. That's another little snippet of information to add to my somewhat limited IT knowledge. It never ceases to amaze me how much is going on behind the scenes when we are using our devices. Whichever persons thought all this up and managed to get it all to work must have been incredibly clever and that's not even taking into consideration the complexities of designing and producing the hardware to run it all.
