Sometimes it is needed to know MAC address of the devices like computers, routers, switch or some others. This article describes how to use MAC address ipconfig command. Click on the Start Menu. Type 'cmd' without quotes and press Enter. At the command prompt, type 'ipconfig /all' without quotes. (space between g and /). What is the IPCONFIG command for MAC OSX? As OSX is based on UNIX you need to type in the following command from a terminal prompt. This has been tested on: OSX Mavericks, Yosemite, EL Capitan. This command should also work for other versions of OSX.

Ipconfig is a TCP/IP utility that displays the current TCP/IP configuration settings for each network interface card (NIC). The ipconfig command is often one of the first commands to use when to check the status of the connection when you experience communication problems on a TCP/IP network.

When you type ipconfig at a command prompt, the following information is displayed for each NIC:

You can display additional information, including the host name, physical address, and Dynamic Host Configuration Protocol (DHCP), Windows Internet Name Service (WINS), and Domain Name System (DNS) configuration, using ipconfig /all.

You can release and renew IP addresses obtained by DHCP using ipconfig /release and ipconfig /renew. Free vst downloads for mac.

Youmay want to customize this slightly - you can change the screencolors or number of columns or rows.

How to use ipconfig

The syntax of ipconfig command is:

Ipconfig parameters explanation

/all : Displays the full TCP/IP configuration for all adapters. Adapters can represent physical interfaces, such as installed network adapters, or logical interfaces, such as dial-up connections.
/allcompartments : Displays the full TCP/IP configuration for all compartments.
/displaydns : Displays the contents of the DNS client resolver cache, which includes both entries preloaded from the local Hosts file and any recently obtained resource records for name queries resolved by the computer. The DNS Client service uses this information to resolve frequently queried names quickly, before querying its configured DNS servers.
/flushdns : Flushes and resets the contents of the DNS client resolver cache. During DNS troubleshooting, you can use this procedure to discard negative cache entries from the cache, as well as any other entries that have been added dynamically.
/registerdns : Initiates manual dynamic registration for the DNS names and IP addresses that are configured at a computer. You can use this parameter to troubleshoot a failed DNS name registration or resolve a dynamic update problem between a client and the DNS server without rebooting the client computer. The DNS settings in the advanced properties of the TCP/IP protocol determine which names are registered in DNS.
/release [<Adapter>] : Sends a DHCPRELEASE message to the DHCP server to release the current DHCP configuration and discard the IP address configuration for either all adapters (if an adapter is not specified) or for a specific adapter if the Adapter parameter is included. This parameter disables TCP/IP for adapters configured to obtain an IP address automatically. To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters.
/release6[<Adapter>] : Sends a DHCPRELEASE message to the DHCPv6 server to release the current DHCP configuration and discard the IPv6 address configuration for either all adapters (if an adapter is not specified) or for a specific adapter if the Adapter parameter is included. This parameter disables TCP/IP for adapters configured to obtain an IP address automatically. To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters.
/renew [<Adapter>] : Renews DHCP configuration for all adapters (if an adapter is not specified) or for a specific adapter if the Adapter parameter is included. This parameter is available only on computers with adapters that are configured to obtain an IP address automatically. To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters.
/renew6 [<Adapter>] : Renews DHCPv6 configuration for all adapters (if an adapter is not specified) or for a specific adapter if the Adapter parameter is included. This parameter is available only on computers with adapters that are configured to obtain an IPv6 address automatically. To specify an adapter name, type the adapter name that appears when you use ipconfig without parameters.
/setclassid [<Adapter> ] : Configures the DHCP class ID for a specified adapter. To set the DHCP class ID for all adapters, use the asterisk (*) wildcard character in place of Adapter. This parameter is available only on computers with adapters that are configured to obtain an IP address automatically. If a DHCP class ID is not specified, the current class ID is removed.
/showclassid [<Adapter>] : Displays the DHCP class ID for a specified adapter. To see the DHCP class ID for all adapters, use the asterisk (*) wildcard character in place of Adapter. This parameter is available only on computers with adapters that are configured to obtain an IP address automatically.
/? : Displays Help at the command prompt.

Usefulness of Ipconfig

This command is most useful on computers that are configured to obtain an IP address automatically. This enables users to determine which TCP/IP configuration values have been configured by DHCP, Automatic Private IP Addressing (APIPA), or an alternate configuration.
If the name you supply for Adapter contains any spaces, use quotation marks around the adapter name (example: “Adapter Name“).
For adapter names, ipconfig supports the use of the asterisk (*) wildcard character to specify either adapters with names that begin with a specified string or adapters with names that contain a specified string. For example, Local* matches all adapters that start with the string Local and *Con* matches all adapters that contain the string Con.

Ipconfig examples

To renew a DHCP-assigned IP address configuration for only the Local Area Connection adapter, type:

To flush the DNS resolver cache when troubleshooting DNS name resolution problems, type:

To display the DHCP class ID for all adapters with names that start with Local, type:
