OpEdge
Industrial Edge Gateway – Release 01.0.00 – 10/2022
5.3.2.1 DHCP Server
The OpEdge can operate as a DHCP server that assigns IP address, DNS server, and default
gateway address configurations to all devices connected via LAN. By default, this feature is
disabled.
Dynamic allocation allows automatic reuse of addresses by granting temporary address leases to
hosts as they are requested. When a lease expires, the host must renew the lease with the
server. If a lease is not renewed, that address may be allocated to a new host. For dynamic
allocation, a set of address pools (or "ranges") are configured on the server and new addresses
are selected from these pools.
To configure the DHCP server on OpEdge:
1
Click the
Networking
tab on the OpEdge configuration webpage.

ERVER
