Displays protocol statistics and current TCP/IP connections using NBT (NetBIOS over TCP/IP).
#NETWORK COMMAND LINE MAC CHEAT SHEET UPDATE#
NBTSTAT: Update cache of the LMHOSTS file. When not specified, the first applicable interface will be used.
adr_if Specifies the internet interface whose address translation table should be modified. The physical address is given as 6 hexadecimal bytes separated by hyphens. -s Adds the host and associates the adr_inet internet address with the adr_eth physical address. -d Deletes the host specified by adr_inet. -N adr_if Displays ARP entries for the network interface specified by adr_if. adr_inet Specifies an internet address. If more than one network interface uses ARP, entries for each ARP table are displayed. If adr_inet is specified, only the physical and IP addresses of the specified computer are displayed. 
-a Displays active ARP entries by interrogating the current data protocol.Displays and modifies the translation tables of IP addresses to physical addresses used by the ARP address resolution protocol. METRIC: Specifies the cost metric for the destinationĪRP: Resolving IP addresses to MAC addresses.Unspecified, it takes the default value of 255.255.255.255. netmask: Provided, it specifies the value of the subnet mask to be associated with this route entry.
MASK: If the MASK keyword is present, the next parameter is interpreted as the network mask parameter. -p Makes the entry into the table, residual (after reboot). Used in conjunction with one of the below "commands", the tables are cleared before executing the command. -f Clears the routing tables of all gateway entries. ROUTE: Displays or modifies the routing table -abnov Displays processes using the internet connection (local IP address, port, remote IP adress and the PID of the process that uses the connection as well as its name). Press Ctrl + C to stop displaying statistics. interval: Re-display the selected statistics, pausing after a specific "interval" (in seconds) between each display. By default, statistics on TCP, UDP and IP are displayed, the -p option can be used to specify a subset. -r Displays the contents of the routing table. Used with the -s option to display per-protocol statistics, proto may be TCP, UDP or IP. -p proto Shows connections for the protocol specified by proto, proto may be TCP or UDP. -n Displays addresses and port numbers in numerical form. -a Displays all connections and listening ports (server-side connections are normally inhibited). NETSTAT: Displays the status of the TCP/IP stack on the local machine /registerdns: Refreshes all DHCP leases and re-registers DNS names. The DNS Client service uses this information to quickly resolve frequently queried names, before querying the configured DNS servers. /displaydns: Displays the DNS client resolver cache, which includes entries preloaded from the local host file and any recently obtained records for name queries resolved by the host computer. This option is useful to exclude negative entries and all other entries added dynamically to the cache. /flushdns: Empty and reset the DNS client resolver cache. This parameter disables TCP/IP for network cards configured to automatically obtain an IP address. /release : Sends a DHCPRELEASE message to the DHCP server to release the current DHCP configuration and cancel the IP address configuration for all adapters (if adapter is not specified) or a specific adapter indicated by the parameter. /renew : Renews DHCP configuration for all adapters (if adapter is not specified) or a specific adapter indicated by the parameter. /all: Displays all network configuration, including DNS, WINS, DHCP servers, etc. This command, when executed with no options, displays the current IP address, the subnet mask and default gateway (network interfaces of the local machine) Ipconfig /all ] ] /flushdns /displaydns /registerdns IPCONFIG: Displays or refresh the TCP/IP configuration This command is useful if the ping command does return any data, to determine at what level the connection failed. TRACERT: Displays all intermediate IP addresses through which a packet passes through, between the local machine and the specified IP address. 
This command is also useful to generate network load by specifying the size of the packet with the -l option and the packet size in bytes. If you specify the -t option you can always get statistics without interrupting pings by pressing Ctrl + Break The -t option to ping continuously until Ctrl-C is pressed. PING: Test the network connection with a remote IP address
