![]() ![]() 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 ICMP Echo Request messages with varying Time to Live (TTL) values to the destination. Used without parameters, tracert displays help. The near-side interface is the interface of the router that is closest to the sending host in the path. The path displayed is the list of near-side router interfaces of the routers in the path between a source host and a destination. Ping -j 10.12.0.1 10.29.3.1 10.1.44.1 10.0.99.221 Tracertĭetermines the path taken to a destination by sending Internet Control Message Protocol (ICMP) Echo Request messages to the destination with incrementally increasing Time to Live (TTL) field values. To ping the destination 10.0.99.221 and record the route for 4 hops, type: To ping the destination 10.0.99.221 with 10 Echo Request messages, each of which has a Data field of 1000 bytes, type: To ping the destination 10.0.99.221 and resolve 10.0.99.221 to its host name, type: The following example shows ping command output: In this case, ensure that the computer name you are specifying can be resolved through the local Hosts file, by using Domain Name System (DNS) queries, or through NetBIOS name resolution techniques. If pinging the IP address is successful, but pinging the computer name is not, you might have a name resolution problem. You can use ping to test both the computer name and the IP address of the computer. Used without parameters, ping displays help. Ping is the primary TCP/IP command used to troubleshoot connectivity, reachability, and name resolution. The receipt of corresponding Echo Reply messages are displayed, along with round-trip times. Verifies IP-level connectivity to another TCP/IP computer by sending Internet Control Message Protocol (ICMP) Echo Request messages. Ipconfig /setclassid "Local Area Connection" TEST Ping To set the DHCP class ID for the Local Area Connection adapter to TEST, type: To display the DHCP class ID for all adapters with names that start with Local, type: To flush the DNS resolver cache when troubleshooting DNS name resolution problems, type: To renew a DHCP-assigned IP address configuration for only the Local Area Connection adapter, type: To display the full TCP/IP configuration for all adapters, type: To display the basic TCP/IP configuration for all adapters, type: This enables users to determine which TCP/IP configuration values have been configured by DHCP, Automatic Private IP Addressing (APIPA), or an alternate configuration. This command is most useful on computers that are configured to obtain an IP address automatically. Used without parameters, ipconfig displays the IP address, subnet mask, and default gateway for all adapters. To add a static ARP cache entry that resolves the IP address 10.0.0.80 to the physical address 00-AA-00-4F-2A-9C, type:Īrp -s 10.0.0.80 00-AA-00-4F-2A-9C Ipconfigĭisplays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. To display the ARP cache table for the interface that is assigned the IP address 10.0.0.99, type: To display the ARP cache tables for all interfaces, type: This command is available only if the Internet Protocol (TCP/IP) protocol is installed as a component in the properties of a network adapter in Network Connections Syntax Used without parameters, arp displays help. There is a separate table for each Ethernet or Token Ring network adapter installed on your computer. Displays and modifies entries in the Address Resolution Protocol (ARP) cache, which contains one or more tables that are used to store IP addresses and their resolved Ethernet or Token Ring physical addresses.
