IP Address Assignment

4-3

DHCP offers dynamic IP address allocation. When a client receives an IP
address, it also receives a lease (an amount of time the host may use the
address). The lease times vary from 1 hour to 100 years, or may be infinite.
When the lease expires, the host must stop using the address. DHCP may
also be used like BOOTP, with a certain IP address always assigned to a
certain device. Depending on the server, both methods may be used at the
same time.

If the MonarchNet does not find a DHCP server after two minutes, it will
timeout and assume a default address of 198.102.102.254. This follows
current BOOTP and RARP behavior.

If the MonarchNet receives multiple responses, it will

choose the first response.

When the MonarchNet receives an address, it sends an ARP message once
every second for five seconds on the offered address to determine if another
device is using it. If the MonarchNet finds another device is using the
address, it will refuse the address and start looking for a new address.

The internal MonarchNet print servers can have the TCP/IP addresses
configured via the front panel menu of the printer. After the IP address,
subnet mask and default gateway addresses have been configured, set the
menu IP SAVE=Yes* to accept the addresses.

B O O T P

Since every TCP/IP network device is required to have a unique IP address
assigned to it, there must be a method of getting that address. Bootp is one
method of assigning IP addresses to hardware addresses. Monarch Bootp
Server
implements a simple (subset) version of the standard Bootp.
