What is Ifconfig? Ifconfig is a system administration utility in Unix-like operating systems for network interface configuration. The utility is a command line interface tool and is also used in the system startup scripts of many operating systems.

In windows I can use ipconfig /all and this displays all the info about my connection. In terminal using ifconfig does not and only supplies limited info. I can use network manager, but it would be useful to know the command line alternative. So my question is: what is the command line to supply ip address, gateway, subnet mask, DNS the same way ipconfig /all supplies in Windows. This short guide will show you how to use the IPCONFIG utility that is commonly used by Microsoft Windows engineers on a Apple Mac OS X Operating System. This can be used to get mac address for remote computers also. Below are few examples on how to use this command. It works on XP, Vista, Windows 7, Server 2003 and Server 2008 operating systems. Get mac addresses from CMD. Just run the command getmac to get the mac. Thank you for choosing Amcrest as your home security solution!

If you momentarily forget where you are at a Mac OS X terminal session, you might type 'ipconfig /all' or something equally Windowish. You will get a response:

usage: ipconfig <command> <args>>
where <command> is one of waitall, getifaddr, ifcount, getoption, getpacket, set, setverbose

What's this? You already know you mistyped: on Mac OS X you probably meant to run 'ifconfig -a' just as you would on Linux. But 'ipconfig' is different, and is actually something good to have in your bag of tricks.

The first thing ipconfig can do for you is quickly give you all your dhcp info:

$ ipconfig getpacket en0
op = BOOTREPLY
htype = 1
flags = 0
hlen = 6
hops = 0
xid = 1045997387
secs = 0
ciaddr = 0.0.0.0
yiaddr = 192.168.9.30
siaddr = 0.0.0.0
giaddr = 0.0.0.0
chaddr = 0:16:cb:8d:38:f7
sname =
file =
options:
Options count is 7
dhcp_message_type (uint8): ACK 0x5
subnet_mask (ip): 255.255.255.0
lease_time (uint32): 0x93a80
router (ip_mult): {192.168.9.254}
domain_name_server (ip_mult): {192.168.9.254}
server_identifier (ip): 192.168.9.254
end (none):

There are shortcuts to the items listed under 'options':

$ ipconfig getoption en0 router
192.168.9.254
$ ipconfig getoption en0 domain_name_server
192.168.9.254

'ipconfig getifaddr en0' is a quick way to just get the ip address.You can also use ipconfig with its 'set' options to change an interface from DHCP to manual or vice-versa. That's temporary; it doesn't write any start up files.

If you are having difficulty with DHCP, ipconfig has one more use: you can (as root) set verbose logging with 'ipconfig setverbose 1'. With that set, you get minor debugging info written to syslog (/var/log/system.log on my system), but you also get a separate BOOTP/DHCP log in /var/log/com.apple.IPConfiguration.bootp that shows the full BOOTREQUEST/BOOTREPLY packet negotiation.

Think of ipconfig the next time you are looking for DHCP info on a Mac.

The ipconfig command is used to find out your current local IP address, default gateway, TCP/IP settings and more. With IPCONFIG you can not only find out your IP Address, find your default gateway and find your subnet mask, you can release and renew, resolve the DNS, troubleshoot internet connections and more. This is a very handy network tool for finding your local IP address as well as many other secrets.

ipconfig cmd explained

ipconfig /all
To display all of your current IP information for all adapters. With ipconfig /all you can also find out your DNS Server and MAC Address. This will show your ethernet adapters full TCPIP configuration for all adapters on your Windows computer. You can find out your own IP Address as well as your default gateway.

ipconfig /release
Use IPCONFIG release to release your current IP information and obtain a new IP Address from the DHCP server.

ipconfig /renew
Use to IPCONFIG renew to renew your IP Address if you have it set to obtain IP Address automatically.

ipconfig /displaydns
This shows your current DNS resolver cache logs. DNS caching basically tells your computer to store the DNS locally. Meaning it now knows what website name is attached to what IP address and it can load faster using the DNS cache instead of having to resolve to it.

ipconfig /flushdns
The Flush DNS Command flushes or clears your current DNS resolver cache logs. If a website were to switch host or get a new IP address, yet still have an old DNS cache, it would direct you to a no longer working site. In this case, you would have to flush the DNS to obtain fresh information upon your next visit. This can happen if a website has a dynamic IP.

ipconfig /registerdns
The register DNS command updates the DNS settings on the Windows computer. It doesn’t just access the local DNS cache, it initiates communication with the DNS server and the DHCP server so it can re-register the network address. You can use this for troubleshooting problems with connection to the ISP (Internet Service Provider), like failing to obtain a dynamic IP address from the DHCP Server or failing to connect to the ISP DNS server.
