What Routers include DHCP servers

DHCP requires disk storage (or some other form of reliable non-volatile storage), making the task of DHCP service more compatible with servers than with dedicated routers. The large-scale routers (i.e., those of Cisco, Bay, Fore) don’t an will probably never will have a DHCP server function.

But there are a number of types of servers that can be configured to route and serve DHCP. This includes Novell servers and computers running Unix. There are also units designed to handle two or more aspects of your Internet connection, e.g. routing between a LAN and a leased line as well as doing other functions to allow computers on the LAN to reach the Internet (or corporate intranet as the case may be). One example is Farallon’s Netopia Internet Router mentioned above under commercial servers.


What Routers forward DHCP requests


(from Cisco FAQ) Routers running GSYS version 9.21(4) and 10.0(3) as well as later releases.


(from Wellfleet FAQ) DHCP is supported by enabling BOOTP support (with transmission and/or reception as needed). Starting with version 9.00 of their routing software BayRs.

3Com Netbuilder

Version 7.2 software can support DHCP relaying through the use of its generic UDP Helper service. Version 8.0 and later officially supports DHCP.


Version 5.5 of their routing software supports DHCP.


The switches’ “router” function has have been handling BOOTP forwarding since around 1993. Support for the broadcast flag introduced in a maintenance release of 2.5 of their software and is in version 2.6 and later.

IBM 2210

I’ve confirmed that Version 1 Release 2 has a BOOTP relay agent. I haven’t found out anything about support for the broadcast flag.


Version 7.2 (about 1994) and later support DHCP relaying.


I’m not sure what is the first version that has this support.

Novell MPR

The same as for their server.

IBM 6611

Supports BOOTP forwarding.


What are the DHCP plans of major client-software vendors?

Apple MacOS

MacTCP’s successor, Open Transport, supports DHCP. Open Transport 1.1 ships with System 7.5 Update 2.0 (which updates MacOS to version 7.5.3, released March 11, 1996) and supports any 68030, 68040, or PowerPC Macintosh. A shrink wrap version of Open Transport is planned.

Microsoft Windows95

supports it and does not support BOOTP. I heard a rumor that BOOTP support will be added.

Novell LAN Workplace for DOS

For supporting DOS/Windows 3.1, Client32 for DOS/Windows, due in June 1996, will provide the TCP/IP stack functions and will support DHCP and BOOTP. For Windows 95 and Windows NT, the native stack will be used so that DHCP is supported.

IBM OS/2 Warp

supports it.
