For a Microsoft Windows 2000 version of this article, see 162326. This article describes TRACERT (Trace Route), a command-line utility that you can use to trace the path that an Internet Protocol (IP) packet takes to its destination. This article discusses the following topics: How to Use the TRACERT Utility How to Use TRACERT to Troubleshoot How to Use TRACERT Options The TRACERT diagnostic utility determines the route to a destination by sending Internet Control Message Protocol (ICMP) echo packets to the destination. In these packets, TRACERT uses varying IP Time-To-Live (TTL) values. Because each router along
the path is required to decrement the packet's TTL by at least 1 before forwarding the packet, the TTL is effectively a hop counter. When the TTL on a packet reaches zero (0), the router sends an ICMP "Time Exceeded" message back to the source computer. TRACERT sends the first echo packet with a TTL of 1 and increments the TTL by 1 on each subsequent transmission, until the destination responds or until the maximum TTL is reached. The ICMP "Time Exceeded" messages that intermediate routers
send back show the route. Note however that some routers silently drop packets that have expired TTLs, and these packets are invisible to TRACERT. TRACERT prints out an ordered list of the intermediate routers that return ICMP "Time Exceeded" messages. Using the -d option with the tracert command instructs TRACERT not to perform a DNS lookup on each IP address, so that TRACERT reports the IP address of the near-side interface of the routers. In the following example of the tracert
command and its output, the packet travels through two routers (157.54.48.1 and 11.1.0.67) to get to host 11.1.0.1. In this example, the default gateway is 157.54.48.1 and the IP address of the router on the 11.1.0.0 network is at 11.1.0.67. The command: C:\>tracert 11.1.0.1 Tracing route to 11.1.0.1 over a maximum of 30 hops Trace complete. You can use TRACERT to find out where a packet stopped on the network. In the following example, the default gateway has found that there is no valid path for the host on 22.110.0.1. Probably, either the router has a configuration problem, or the 22.110.0.0 network does not exist,
reflecting a bad IP address. The command: C:\>tracert 22.110.0.1 Tracing route to 22.110.0.1 over a maximum of 30 hops Trace complete. How to Use TRACERT OptionsThere are several command-line options that you can use with TRACERT, although the options are not usually necessary for standard troubleshooting. The following example of command syntax shows all of the possible options: tracert -d -h maximum_hops -j host-list -w timeout target_hostWhat the parameters do: -d -h maximum_hops -j host-list -w timeout target_host Need more help?Asked by GrandSeaUrchin249 a)SNMP b)ICMP c)Telnet d)TCP a)traffic analysis b)network documentation c)device inventory d)cost analysis a)changing system passwords every 30 days b)providing all systems with descriptions

In these packets, TRACERT uses varying IP Time-To-Live (TTL) values.
Which protocol is used by the traceroute command to send and receive echo requests and echo replies ICMP SNMP TCP Telnet navigation bar?Traceroute sends a series of ICMP echo request packets to a destination.
What protocol is used by traceroute?Traceroute most commonly uses Internet Control Message Protocol (ICMP) echo packets with variable time to live (TTL) values. The response time of each hop is calculated.
Is traceroute ICMP or TCP?Traceroute uses ICMP's Ping command to find out how many different devices are between the computer initiating the traceroute and the target. This command works by manipulating the packets time to live value or TTL.
