to go back over again; "we retraced the route we took last summer"; "trace your path"

a utility that traces a packet from your computer to any other host, showing how many hops the packet requires to reach the host and how long each hop takes. If you're visiting a Web site and pages are appearing slowly, you can use traceroute to figure out where the longest delays are occurring. Trace utilities work by sending packets with low time-to-live (TTL) fields. The TTL value specifies how many hops the packet is allowed before it is returned. When a packet can't reach its destination because the TTL value is too low, the last host returns the packet and identifies itself. By sending a series of packets and incrementing the TTL value with each successive packet, traceroute finds out who all the intermediary hosts are.

A TCP/IP utility that allows you to determine the route packets are taking to a particular host. Trace route works by increasing the "time to live" value of packets and seeing how far they get, until they reach the given destination.

(1) A relative term, usually referring to a supposed insignificant quantity of an undesirable alloying element or undesirable type of material. Since the term refers to an inexact quantity, it should be used with care. (2) To trace a RR car is to determine through inquiry of a carrier, where in its route a car may be located at any time. We often need to trace cars that have been slow in getting delivered to destination, or if we intend to consider the reconsignment of a car to another destination, and need to know whether its location is in or out of route.

(track) Segment of a route. See conductor.

This utility determines the route taken to a destination by sending echo packets to the destination. For e.g. tracert mydomain.com will display different destination route from your PC to destination server. Useful to find breakage between routes.
