As DHCP is implemented as an option of BOOTP, you can only filter on BOOTP messages. A complete list of BOOTP display filter fields can be found in the display filter reference Show only the BOOTP based traffic:

If you want to distribute IPv4 addresses to known clients only (static leases), use: . uci set dhcp.lan.dynamicdhcp= "0" uci commit dhcp / etc / init.d / dnsmasq restart. With this, dnsmasq will consider static leases defined in “config host” blocks and in /etc/ethers, and refuse to hand out any IPv4 address to unknown clients.. Note that you shouldn't use this as a security feature to DHCP configuration file /etc/dhcp/dhcpd.conf explained # Hosts for which fixed IP addresses have been specified can boot using # BOOTP or DHCP. Hosts for which no fixed address is specified can only # be booted with DHCP, unless there is an address range on the subnet # to which a BOOTP client is connected which has the dynamic-bootp flag # set. Configure an IPv4 DHCP Server - WatchGuard Configure an IPv4 DHCP Server. DHCP (Dynamic Host Configuration Protocol) is a method to assign IP addresses automatically to network clients. You can configure your Firebox as a DHCP server for the networks that it protects. If you have a DHCP server, we recommend that you continue to use that server for DHCP.

The Dynamic Host Configuration Protocol (DHCP) makes it possible for communication hardware (such as routers, hubs, or switches) to automatically assign an individual address to connection-seeking devices and integrate them into a network. Ideally, there’s only a single server so that there are no complications with the assignment. Windows Server : Integration between DNS and DHCP

Set Static Addresses from DHCP. This is my favorite thing. You may assign static IP addresses to your LAN hosts by MAC address, or by hostname. The address must fall in a range you have already configured with dhcp-range=: dhcp-host=d0:50:99:82:e7:2b,192.168.10.46 dhcp-host=turnip,192.168.10.45
