In this case, a row of asterisks ( *) is displayed for that hop. However, some routers do not return time Exceeded messages for packets with expired TTL values and are invisible to the tracert command. The path is determined by examining the ICMP time Exceeded messages returned by intermediate routers and the echo Reply message returned by the destination. The maximum number of hops is 30 by default and can be specified using the /h parameter. This command determines the path by sending the first echo Request message with a TTL of 1 and incrementing the TTL by 1 on each subsequent transmission until the target responds or the maximum number of hops is reached. When the TTL on a packet reaches 0, the router is expected to return an ICMP time Exceeded message to the source computer. Effectively, the TTL is a maximum link counter. Each router along the path is required to decrement the TTL in an IP packet by at least 1 before forwarding it. This diagnostic tool determines the path taken to a destination by sending Internet Control Message Protocol (ICMP) echo Request or ICMPv6 messages to the destination with incrementally increasing time to live (TTL) field values. Note: If you cannot trace the LexisNexis servers, your traceroute report times out after displaying these internet addresses.Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012 The following traceroute entries indicate that you are receiving return packets from the LexisNexis routers: Routing information for the host exists, but the host is not responding or the host computer is off and unable to respond to the request. The last host's routing table does not contain an entry for the network or the host you want to reach. There is no known path to the requested host. The system administrator for your network has blocked the traceroute at a certain point. If this point is appearing at the end of the traceroute, there could be an issue with a LexisNexis router.If this point is appearing anywhere in the middle of the traceroute, there could be an issue with your internet service provider.This indicates a possible issue with your firm's network. If this point is appearing in the first 1-3 hops, the packets may not be making it out of your firm's network.If every packet beyond a certain hop returns asterisks, you could have a problem with a router/gateway after the last successful hop. This is due to the ICMP (Internet Control Message Protocol) blocking traffic or the packet did not reach the intended destination and timed out. If you receive asterisks, your results did not return within the TTL (time to live) value. Note: Use the URL or to run a traceroute to the LexisNexis ® Services. Consistent indications of transmission times that exceed 600 milliseconds indicate a possible connectivity problem. Packets that fail to return (dropped packets) are indicated with an asterisk (*). The traceroute report displays these items in a list. The traceroute application times the transmission of these packets to every hop between your computer and the targeted destination terminal. Each time traceroute receives packets, it sends three new packets. The traceroute application sends three packets from your computer to your traceroute destination and waits for them to return. Enter the IP address or web address for the destination site and click Trace.Double-click Network Utility from the Top Hit list. Enter Network Utility into the Spotlight Search field.Note: The icon looks like a magnifying glass. Click the Spotlight icon in the Menu bar.Take the following steps to run a traceroute in Mac OS ®: Enter tracert, a space, then the IP address or web address for the destination site (for example: tracert.Enter cmd and press Enter to open a Command Prompt.Press Windows key + R to open the Run window.Take the following steps to run a traceroute in Microsoft ® Windows ®: Before using Traceroute, you can use the Ping utility to identify whether a host is present on the network. This utility helps you find where high transfer times are occurring in your internal network and the Internet. It also calculates and displays the amount of time for each hop. Traceroute is a utility that records the Internet route (gateway computers at each hop) between your computer and a specified destination computer.
