As shown in
DNS server address, and static route information. The DHCP client IP address resides on network
10.1.1.0/24. The DNS server address is 20.1.1.1. The next hop of the static route to network 20.1.1.0/24
is 10.1.1.2.
The DHCP server uses Option 121 to assign static route information to DHCP clients.
Option 121 format. The destination descriptor field contains the following parts: subnet mask length and
destination network address, both in hexadecimal notation. In this example, the destination descriptor is
18 14 01 01 (the subnet mask length is 24 and the network address is 20.1.1.0 in dotted decimal
notation). The next hop address is 0A 01 01 02 (10.1.1.2 in dotted decimal notation).
