For some reason when I enter ipconfig in terminal, it just returns this:
No command 'ipconfig' found, did you mean:
Command 'tpconfig' from package 'tpconfig' (universe)
Command 'iwconfig' from package 'wireless-tools' (main)
Command 'ifconfig' from package 'net-tools' (main)
ipconfig: command not found
Not quite sure what the issue is here or how to approach this
The Ubuntu/Linux equivalent of ipconfig in Windows is ifconfig.
Try typing sudo ifconfig.
The result will look something like this:
eth0 Link encap:Ethernet HWaddr 00:0c:29:94:37:b6
inet addr:192.168.1.231 Bcast:192.168.1.255 Mask:255.255.255.0

If that's the case, use ifconfig. It'll give you the same output that ipconfig will on Windows. But ifconfig is now ip a.
ifconfig
is equivalent to
ip addr show
and, because the object argument can be abbreviated and command defaults to show, also to
ip a
ipconfig is a Windows program - the closest for linux is ifconfig, but contrary to what others (including the accepted "answer") are saying, it is not the same, and does not give the same output at all.
One of the key missing pieces of information in ifconfig is the DNS addresses; they are not there, and there's not an easy way to find that out. On my system, I have an alias to show some information like that:
nmcli dev list iface eth0 | grep IP4
This will list most of the information I usually want to see. On my system, it shows:
$ nmcli dev list iface eth0 | grep IP4
IP4-SETTINGS.ADDRESS: 192.168.1.110
IP4-SETTINGS.PREFIX: 24 (255.255.255.0)
IP4-SETTINGS.GATEWAY: 192.168.1.1
IP4-DNS1.DNS: 8.8.8.8
IP4-DNS2.DNS: 8.8.4.4
Note that you may need to use a different designation for the network, such as eth1, eth2, etc. If you get an error about a device not found, try changing this.
Also note the accepted "answer" is also incorrect in that you do not need to use "sudo" for this command.
2020 UPDATE (Ubuntu 18+)
Still, use nmcli as an equivalent command as Marty Fried suggests.
Coming from Windows, when you do ipconfig you probably expect to see a bunch of information such as the network interfaces, ipv4, ipv6 addresses, dns server, default gateways etc. Unfortunately, and as Marty Fried mentions in his answer, ifconfig is hard to extract this information (I'm not even sure it has it at all) so I would say ifconfig and ip addr show are not really equivalent commands to ipconfig because they are missing all this information.
However you can use nmcli:
nmcli dev show eth0
Explanation:
You can first list all your network interface devices to get the device name:
nmcli dev show | grep DEVICE
output
: '
GENERAL.DEVICE: wlp5s0
GENERAL.DEVICE: br-877527cf5a41
GENERAL.DEVICE: docker0
GENERAL.DEVICE: enp3s0
GENERAL.DEVICE: veth9938f55
GENERAL.DEVICE: veth9d03338
GENERAL.DEVICE: lo
'
or to also see the network device type:
nmcli dev show | grep -E 'DEVICE|TYPE'
output
: '
GENERAL.DEVICE: wlp5s0
GENERAL.TYPE: wifi
GENERAL.DEVICE: br-877527cf5a41
GENERAL.TYPE: bridge
GENERAL.DEVICE: docker0
GENERAL.TYPE: bridge
GENERAL.DEVICE: enp3s0
GENERAL.TYPE: ethernet
GENERAL.DEVICE: veth9938f55
GENERAL.TYPE: ethernet
GENERAL.DEVICE: veth9d03338
GENERAL.TYPE: ethernet
GENERAL.DEVICE: lo
GENERAL.TYPE: loopback
'
In my case I'm only interested in my wifi so i'm going to use the GENERAL.DEVICE name of my GENERAL.TYPE: wifi and:
nmcli dev show wlp5s0
output
: '
GENERAL.DEVICE: wlp5s0
GENERAL.TYPE: wifi

Here's a function you can add to ~/.bashrc or ~/.bash_aliases:
function ipconfig() {
for i in `seq 1 100`; do printf "-"; done; echo "";
nmcli dev show $1 | grep -E 'DEVICE|TYPE|HWADDR|MTU|STATE|CON|ADDRESS|GATEWAY|ROUTE|DNS|DOMAIN|^$' | awk '!NF{for(i=0; i<=100; i++) printf "-";}1';
for i in `seq 1 100`; do printf "-"; done; echo "";
}
Usage:
ipconfig # show details of all devices
ipconfig eth0 # show only details of eth0
