I believe you need to use the alias keyword to set multiple ip addresses on
an interface.

See this handbook article on how to set it in /etc/rc.conf

https://www.freebsd.org/doc/handbook/configtuning-virtual-hosts.html

See the ifconfig(8) man page for how to set it on the fly:

http://man.freebsd.org/ifconfig


Good luck!
