Your Internet connection has no Reverse DNS
Many Internet connection IP addresses are associated with a DNS machine name. (But yours is not.) The presence of "Reverse DNS", which allows the machine name to be retrieved from the IP address, can represent a privacy and possible security concern for Internet consumers since it may uniquely and persistently identify your Internet account — and therefore you — and may disclose other information, such as your geographic location.
When present, reverse DNS is supported by Internet service providers. But no such lookups are possible with your current Internet connection address (XXX.XXX.XXX.XXX). That's generally a good thing.
