I'm not sure template is the wrong word.  But, I think we're just
arguing terminology now.  To me, calling it a template indicates that
it must be combined with something else before it is usable for our
purpose.  Here are some options for what to call the attribute:

gateway_ip_template: ''
gateway_ip_host:  ''
gateway_ip_host_part:  ''

I'm sure there are 100 other names we could use.  The key take-aways
for me are that we don't use '*.*.*.1' and that we don't pass the
host-only part of the address as the 'gateway_ip'.  So, these are
wrong IMO:

gateway_ip:  ''
gateway_ip_template: '*.*.*.1'
gateway_ip_host_port: '*.*.*.1'
