DHCP Server Settings
DHCP  stands  for  Dynamic  Host  Control  Protocol.  The  DIR-655  has  a  built-in  DHCP  server.  The  DHCP  Server  will 
automatically assign an IP address to the computers on the LAN/private network. Be sure to set your computers to be 
DHCP clients by setting their TCP/IP settings to “Obtain an IP Address Automatically.” When you turn your computers 
on, they will automatically load the proper TCP/IP settings provided by the DIR-655. The DHCP Server will automatically 
allocate an unused IP address from the IP address pool to the requesting computer. You must specify the starting and 
ending address of the IP address pool.
Check this box to enable the DHCP server on 
your router. Uncheck to disable this function.
Enter the starting and ending IP addresses for 
the DHCP server’s IP assignment.
Note:  If  you  statically  (manually)  assign  IP 
addresses to your computers or devices, make 
sure the IP addresses are outside of this range 
or you may have an IP conflict. 
The  length  of  time  for  the  IP  address  lease. 
Enter the Lease time in minutes.
Enable this feature to broadcast your networks 
DHCP server to LAN/WLAN clients.
NetBIOS  allows  LAN  hosts  to  discover  all 
other  computers  within  the  network,  enable

DHCP Reservation
If you want a computer or device to always have the same IP address assigned, you can create a DHCP reservation. 
The router will assign the IP address only to that computer or device. 
Note: This IP address must be within the DHCP IP Address Range.
Check this box to enable the reservation.

Reserve:
Note:  The Revoke option will not disconnect a PC with a current network session from the network; you would need to use 
MAC Address Filter to do that. Revoke will only free up a DHCP Address for the very next requester. If the previous 
owner is still available, those two devices may both receive an IP Address Conflict error, or the second device may 
still not receive an IP Address; in that case, you may still need to extend the “DHCP IP Address Range” to address 
the issue, it is located in the DHCP Server section.  
The Reserve option converts this dynamic IP allocation into a DHCP Reservation and adds the corresponding entry to the 
DHCP Reservations List.
