Symptoms

When running a traceroute on Last Mile, the IP Address and Host Name are often the same, unlike Backbone traceroutes, which resolve to proper Host Names.

Solution

Because Last Mile peers are often private machines running on a commercial Internet connection (like your home computer), often no formal name resolution has been configured for those results. This isn't always the case, but is relatively common, and should be considered expected behavior.
