That's correct. I have 4 specific subnet's I'm looking for in this
example. A host may have zero interfaces on one of the specific
subnets or just 1. I was wanting to return the ipaddress that the
host has on one of the specific subnets.

I was hoping I would be able to ask facter for the information as it
already contains it. I just couldn't even figure out how to begin
formulating such a question (like trying to decide where to bite into
an oversized submarine sandwich!). After Ashley's response and lack
of other ideas I put together the following custom fact which will
return the ipaddress the host has on the specific subnet's (if the
host has one). I've not ventured down the custom fact road before so
this should be an little adventure.
Facter.add("nsd_gateway") do
setcode do
# Get the array of ip's on the machine
output = %x{/sbin/ifconfig -a}
ip = []
# Put the ip addresses into the ip array
output.each_line do |s|
ip.push($1) if s =~ /inet\s+([0-9]+\.[0-9]+\.[0-9]+\.[0-9]+)/
end
ip.grep(/(14.1.22.|19.7.28.|15.0.8.)/)
end
end

Thanks for the alternate idea on using templating to solve the
problem. I had not thought of that approach!
Thanks! Derek
