Help Setting up DHCP scope

spiceuser-kdol9 · 2020-11-19T07:59:38.000Z

Hi, hoping someone can help. Have barely any networking knowledge.

If the server IPv4 address is 192.168.0.1, the start and end would be 192.168.1 and 192.168.1.254, The subnet i assume is 255.255.255.0.

I don’t think i need to add exclusions or delays.

Default gateway I’m not sure what I should put for this. Bare in mind the server I’m using is on a virtual machine.

Not sure if i need to fill the domain name and DNS Servers part?

I have had a play around and just cant get the DHCP to work. The DHCP post-install configuration wizard keeps throwing an erorr about registry key and an error.

Couple of questions

1st) Are you the LAN Admin/Network Admin for this setup?
If not, your LAN admin should be able to tell you what IP address range you need in your scope, the subnet mask to use, the default gateway to use, and the DNS IP addresses. I’m going to assume that you are the admin and move on to my next question.

2nd) Is this the only subnet on your network?
If so and you stated your server’s IP addresss is 192.168.0.1, I would set your range to start at 192.168.0.2 (since your server is already using 19.168.0.1) and end at 192.168.0.254. I will assume that you’re only using 1 subnet mask and not a more complicated network setup for the next question.

3rd) Is your server setup with a static IP address and able to reach the internet?
If so, you can find the IP address settings on the server and use those in your scope (Subnet mask, Default Gateway, and DNS).

I hope at least some of this is helpful

It looks like you are configuring DHCP remotely via server manager. That is OK but I would prefer to configure it locally if I have set the server up with a GUI.

The default gateway would be set up on your central router/firewall as an interface and is usually, but not always .1 or .254. the Subnet Mask would control the number of clients you can address with /24 being a maximum of 254.

If it was me, I would look at starting the DHCP scope on .10 or .100 depending on the number of clients required, then you have spare IPs that you can exclude for static IPs.

The domain name and DNS servers, both are mandatory if you are using Active Directory, you would put in two IP addresses, these would normally be your DCs but some sites will have separate DNS servers. The domain name should match the AD domain name of your organisation.

Thanks for the replies.

Im using a lab enivronment. Ive been tasked with configuring the server with DHCP,DNS and also ADDS. I then need to open hyper V on the server and connect 3 desktops to the domain. Ive failed every try. I for the life of me cannot get the DHCP to work. i know my server ip is 192.168.0.1 but im told the network addrss is 192.168.1.9/24 and the default gateway address is the first usable address on the network.
