DNS not working

I have a dedicated server with a hosting company that went down for 4
days. They finaly got me back up but now with a different IP address. I
noticed that I couldn't send email and after trouble shooting that I
found that I can ssh in to the server but once in the server can't
connect or find anything.

When I execute commands like host yahoo.com, or whois or ftp or
anything like that the server comes back saying host cannot be found?

Any pointer would be appreciated

thanks

Sounds like a good reason to find a new hosting company

What operating system on the server? What distribution and release?

Start with 'uname -a'. If it's Linux, look in /etc/ for a file with a
name ending in 'release' or 'version' - like /etc/redhat-release - and
see what's in that file. That is assuming you have access to the real
/etc/ and are not chroot'ed elsewhere.

You're posting to a Linux group, so if we assume it's Linux, look at
the contents of

/etc/resolv.conf
/etc/host.conf
/etc/nsswitch.conf

Also look at the output of the command '/sbin/iptables -L'
