Appendix 1: ISC DHCP server

One DHCP server that has been tested against DHCP snooping is ISC DHCP. This is free software with an option of a support contract. At the time of writing this document, ISC DHCP did not support the logging of RFC3993 sub-option 6. For convenience, here is a sample configuration (dhcpd.conf) for ISC DHCP.

This configuration lets you specify the IP that is given to each MAC address. You may easily write a range statement to assign to any client.

option domain-name "test.yourdomain.com"; option domain-name-servers 172.16.1.253; option broadcast-address 172.16.1.255; option subnet-mask 255.255.255.0; use-host-decl-names on;
