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.

Thanks all

The only thing missing from ifconfig are the gateway and DNS servers.

15.04 and newer

To get the DNS and Gateway info just type:

nmcli dev show eth0

The output lists some device parameters including some IP4.DNS[x] entries, which show the DNS servers and a IP4.ADDRESS[1] line which lists the IP and Gateway used (look for the gw = ???.???.???.??? part at the end of the line).

Replace eth0 with the actual device name you're using, which may not be the same. To get a list of devices and their status type:

nmcli dev status

Up to and including 14.10

You can get these with nm-tool (in Ubuntu versions prior to 15.04) which BTW is the command line version of network manager.

To run it just type in a terminal:


If you're using Ubuntu 15.04 or newer the nm-tool has been replaced by the nmcli command which is different. Check the section called "15.04 and newer" above this one in this case.

this doesn't work in 15.04 – Klyn Jun 1 '15 at 2:59
@Klyn Edited with new info for 15.04. – devius Jul 23 '15 at 11:59
Using nmcli dev show eth0 results in this: Error: 'dev' command 'show' is not valid. – Enkouyami Jul 27 '15 at 15:42
@Enkouyami What Ubuntu and nmcli versions are you using? – devius Jul 27 '15 at 17:51
@devius nmcli v0.9.8.8 on Ubuntu 15.04. – Enkouyami Jul 28 '15 at 9:33

ipconfig shows things like hostname, DNS servers, those are in a different place than just IP addresses in linux, so you will need a couple of commands.

ifconfig -a
cat /etc/resolv.conf

That shows what I want to see 99% of the time, but ipconfig /all also shows things like DHCP lease times and servers.

cat /var/lib/dhcp/dhclient.leases

Was looking at few links and finally found the below working:

$ nmcli dev list|grep IP4

The output is:

IP4.ADDRESS[1]: ip =, gw =


IP4.DOMAIN[1]: local

Also all the network related details can be found using putting simply: $ nmcli dev list eth0

Hope this helps.

I needed to work out what DHCP server I was connected to via Ubuntu 14.04 so I used this command:

nmcli dev list|grep DHCP4

as this is what I wanted only from the original command "nmcli dev list"

DHCP4.OPTION[1]: expiry = 1464073312

DHCP4.OPTION[2]: domain_name = [omitted_proper_details]

DHCP4.OPTION[3]: broadcast_address =

DHCP4.OPTION[4]: dhcp_message_type = 5

DHCP4.OPTION[5]: dhcp_lease_time = 432000

DHCP4.OPTION[6]: ip_address =

DHCP4.OPTION[7]: subnet_mask =

DHCP4.OPTION[8]: dhcp_renewal_time = 216000

DHCP4.OPTION[9]: routers =

DHCP4.OPTION[10]: domain_name_servers =

DHCP4.OPTION[11]: dhcp_rebinding_time = 378000

DHCP4.OPTION[12]: network_number =

DHCP4.OPTION[13]: dhcp_server_identifier =

Gives me all the DCHP/DNS details I need, just like "IPCONFIG /ALL"
