There appears to be a way of associating a subnet in the IN-ADDR.ARPA 
domain to a FQDN, which could then be queries for LOC data.  For single 
addresses, the domain owner could opt to include location data for their 
domain.  For subnets, the operator can include location data at their 
option.

Also, I would add one more field to the LOC RR:  country code.  This 
would be a two-byte value that is the standard two character ASCII 
country code.  When missing, a value of binary zero would be returned on 
query.
