Assign an IP address directly to the device via the MAC (Media Access Control) address using the ARP (Address Resolution Protocol) command.

For example, let’s assign IP address 192.168.1.200 to a MAC address of 00-aa-00-62-c6-09.

arp -s 192.168.200 00-aa-00-62-c6-09

To make sure it assigned the IP to the MAC address, run the “arp -a” command to display the ARP table.

arp -a
Then, if your device has a browser based interface, open any browser of your choice and then enter the IP address of the device to connect to.

ARP
Displays and modifies the IP-to-Physical address translation tables used by

address resolution protocol (ARP).

ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr] [-v]

-a Displays current ARP entries by interrogating the current protocol data. If inet_addr is specified, the IP and Physical addresses for only the specified computer are displayed. If
more than one network interface uses ARP, entries for each ARP table are displayed.
-g Same as -a.
-v Displays current ARP entries in verbose mode. All invalid entries and entries on the loop-back interface will be shown. inet_addr Specifies an internet address.
-N if_addr Displays the ARP entries for the network interface specified
by if_addr.
-d Deletes the host specified by inet_addr. inet_addr may be
wildcarded with * to delete all hosts.
-s Adds the host and associates the Internet address inet_addr
with the Physical address eth_addr. The Physical address is
given as 6 hexadecimal bytes separated by hyphens. The entry
is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet address of the
interface whose address translation table should be modified.
If not present, the first applicable interface will be used.
Example:
> arp -s 157.55.85.212 00-aa-00-62-c6-09 …. Adds a static entry.
> arp -a …. Displays the arp table.
