I assume your use case does not assume some radio only, etc. networks - and other anomalies, and that's OK - as you know how "your" network is connected to the Internet and others.Since your use case seems to omit the circumstance a user may not have such connection, yet access to 44.60.44.3 assumes connection - as I noted normal PTR records are OK if one happens to make such a lookup.Again, thank you for your consideration.- KB3VWG
