Dynamic DNS Updates

[Evan Sayer]

	FreeBSD-
I would like to know how to make my server running 4.9 update my 
networks Dynamic Ip  address on my domains DNS servers.  My ip is 
always changing because it's dynamic, so a domain is essentially 
pointless unless i can get this up and running.  You could say i want 
my domain to function as though it were assigned to a Static IP.  I 
have been googleing for hours, and i can't understand any of it.  
Please be advised, i am somewhat new to FreeBSD.

Thanks a lot.
