DHCP

Here is the situation...

We have 8 ip ranges 48 - 55 and our current DHCP server is running on 48 along with all of our servers and static IP's. 49 is currently the DHCP addresses which are given out to the pc's on the network. 50 is not used, 51 is another set of static ip's for remote connections, 52 -55 not used. My question is, can we keep the dhcp server on 48 and move the dhcp addresses down to use 53 and 54? i have been told that you are not able to skip ranges and you have to have your dhcp server and addresses in consecutive ranges like we have it with 48 and 49.

thanks

It should work, as experience tells me it does.

However, is there any reason why you want to keep the separate subnets and not just combine all into 1 subnet (255.255.249.0)?  Security? Orginization?  You can then just use "exlcusions" to define which IP Address "Ranges" get handed out to the PCs.

We run a very simialr setup at the office.

When you say "ranges" do you mean subnets?

So you have 192.168.48.x through 192.168.55.s? and your subnet is set as 255.255.255.0? (which means you technically have 8 different networks)

Worried about phishing attacks?

90% of attacks start with a phish. It’s critical that IT admins and MSSPs have the right security in place to protect their end users from these phishing attacks. Check out our latest feature brief for tips and tricks to keep your employees off a hackers line!

well im not very knowledgable with this stuff but this is how it was given to me...

48 and 49 are both on the same subnet, 51 is on its own subnet. So i guess the problem is that they want to keep 48 and 53 & 54 on the same subnet. I was told that you arent able to skip another subnet.

Thanks again

True.
If you are going to "break-Up" the subnets like that, you will run into issues.   An option to consider is to move the DHCP server up to 52, since the subnets "below" it all have Static IPs or assigned by another proccess.(remote connections probably get handled through RAS or the firewall...correct?) and then you can create a new subnet just for PC's.

When they are all private IP address it does not make a difference if you skip a subnet.  You can get concerned when your ISP hands you two totally different ranges.

so will the dhcp server and users be able to see the statics then? Or will we have to add all of them to the host file or something?

Make sure you have them in the correct VLAN and it will work itself out.  The DHCP server will find them just fine.  If your crossing over routers however make sure you have a relay.
