Different subnets or reserved ranges for each server will certainly give you what you want.
If the two servers are part of an Active Directory Domain with DHCP running on the AD box then whichever server you authenticate onto should replicate itself to the other server but if you haven't got a domain then there is a high chance of having duplicate IP's issued if you don't apply restricted IP ranges to each DHCP server.

It is one of the things I've never found "best practice", if there is such a thing, just different opinions. Even the MCSEs I know tend to look blank at me on this one...! Bigger networks will have wired and wireless devices so I wouldn't think I'm doing anything out the ordinary. Not even sure if I should care if it is the first responder giving the IP address, this never seems to be the server in any case as it is always the higher range. Different subnets sounds interesting though, I'll have a read on that one. -----Original Message----- From: ProFox [mailto:[email protected]] On Behalf Of Ted Roche Sent: 23 February 2016 11:39 To: [email protected] Subject: Re: [NF] Two DHCP servers on a network - Changed to [NF] On Tue, Feb 23, 2016 at 3:42 AM, Graham Brown <[email protected]> wrote: > > My thinking was if anything logs into the domain it will take the > server DHCP IP address range and wifi devices from the router DHCP IP range. > I think this is wishful thinking. On startup, the ethernet devices essentially broadcast a plea over the network, "Who can give me an IP address?" and pick one of the responders. IIRC, the first to answer, but no guarantee who. > It appears it is a bad idea to have 2 DHCP servers but not sure if > this will stop the tablets and smartphones getting a connection. It sounds like a bad idea to me. Is there a reason why you can't just turn off the DHCP server on the Win 2012 box? https://technet.microsoft.com/en-us/library/cc778064(v=ws.10).aspx -- Ted Roche Ted Roche & Associates, LLC http://www.tedroche.com [excessive quoting removed by server] _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://mail.leafe.com/mailman/listinfo/profox OT-free version of this list: http://mail.leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[email protected] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
