yum update errors

[Michael neese]

I have errors when using yum...

yum update
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://www.atomicorp.com/mirrorlist/atomic/centos-5-x86_64 error was
[Errno 4] IOError: <urlopen error (113, 'No route to host')>
Error: Cannot find a valid baseurl for repo: atomic

ASL says i have network issues...

arp -n
Address HWtype HWaddress Flags Mask Iface
74.208.8.251 ether 00:00:5e:00:01:f0 C eth0
74.208.2.14 (incomplete) eth0
74.208.155.133 (incomplete) eth0
10.255.255.1 ether 00:00:0c:07:ac:00 C eth0

1and1 says it is because my ip needs to be changed to dchp instead of static...they cannot help me with this, nor can i find solution on the internet...

Can anyone guide me to some way to correct this networking issue?

Is this address accessible from your server?
Check it with something like:

$ host www.atomicorp.com
www.atomicorp.com is an alias for atomicorp.com.
atomicorp.com has address 74.208.155.133

$ ping 74.208.155.133

Contact your system administrator for fixing this usual linux administrative task if you cant do it by yourself.

Thanks for your reply, Igor...

As it turns out, I had installed two new ip's to the server, and mis-configured one with incorrect sub-masking, this screwed up my networking in a big fashion...

It is now Okay and working fine...
