ifconfig doesn't display ipv4 address

[stuckerisg]

Hello, I am very new to Linux after working with IBM AIX for over 20 years.

First time setting up Red Hat Enterprise v6. I used the setup utility to set a static IP address. Now when I run ipconfig it displays the IPv6 address, but not the IPv4 address. The setup utility does show the correct IPv4 address that I entered. I can't ping the IP so I am wondering how I verify that it has the correct IPv4 address. ifconfig does show the interface is up.

Any help would be appreciated. Thanks

Hello and welcome

which command did you run to configure the ipv4 address?
It anyway should modify files under /etc/sysconfig/network-scripts/ifcfg-<DEVICENAME>
You can cat or less these,
or even modify directly if needed.

The ipv6 address is at least the link local, which is always present.

To look at the actual interfaces, you can use ifconfig, as you know.
But also

ip addr show

Thank you for the response. I used setup to configure the ip. If I go to /etc/sysconfig/sysconfig/network-scripts and vi ifcfg-eth0 it does show the correct IPv4 IP address. When I run ip addr show I get the following:
eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:50:56:a8:66:23 brd ff:ff:ff:ff:ff:ff
inet6 fe80: :250:56ff:fea8:662f/64 scope link
valid_lft forever preferred_lft forever

Everything looks good to me, I just want to verify the IPV4 address, as I can't ping it.

Thanks

There is no ipv4 address.
I assume you are on a local or out-of-band console.
Try

ifdown eth0
ifup eth0
dmesg
ip addr show 

or 
/etc/init.d/network stop
/etc/init.d/network start
ip addr show

This worked! I did try using the service command to make sure the network services were up, so ifdown\ifup actually restarts the nw interface? Now ifconfig does show me the IPv4 address and I can ping the server fine.

Thanks so much for your help. Like I said I am a noob so I know I will be posting more.

Be aware that just because you configured an ip address you still need to start the interface.
