Today I realized that most of the addresses that had issues with incorrect locations of the network map may have been related to old and expired reverse DNS entries. Apparently part of our supernet DNS wasn’t being deleting old reverse lookup entries. Of all the misplaced network nodes, the entries seemed to all corresponded to that part of the supernet. We’ll have to wait about a week for the DNS service to finally clean out it’s lists, but I’m hopeful that that’s the reason for the jumping nodes!
