Anyone seen where the map results are showing old devices that no longer exit? I am seeing a bunch of servers that were taken offline still showing on recent map reports.
Sorry you are seeing results you do not expect.
If you select the black arrow to the left of the host in question, it will identify the Discovery Method. DNS is a likely culprit.
The discovery methods are:
ICMP. The mapping service received an ICMP packet from the host.
TCP Port. The mapping service detected open TCP port <number>.
UDP Port. The mapping service detected open UDP port <number>.
DNS. The mapping service resolved a name within the domain into this host's IP address.
Reverse DNS. The mapping service resolved the host's IP address into a name within the domain.
DNS Zone Transfer. Detected via Zone Transfer.
TCP RST. The mapping service received TCP Reset packets from this host.
Traceroute. The mapping service discovered this host via traceroute.
Other Protocol or ICMP. The mapping service received an IP packet from this host whose protocol is not TCP, UDP, or ICMP.
Other TCP Ports. The mapping service received TCP packets whose source ports are not in the list of probed ports.
Please let me know if you need anything else, or have any questions.
