Thanks All,
Answering multiple questions:
*** I started off with Google's DNS servers- 8.8.8.8 and 8.8.4.4 with the same results. The current set were copied off other working wkstas on the LAN . Same type results with "ping www.yahoo.com" and "ping www.yahoo.com". Just changed it to: (1) 8.8.4.4 (2) 216.146.36.36 (3) 8.8.8.8
Rebooted the box, then . . .
root@pbx:~ $ cat /etc/resolv.conf search isp.com nameserver 8.8.4.4 nameserver 216.146.36.36 nameserver 8.8.8.8 root@pbx:~ $ ping www.henrichs.org ping: unknown host www.henrichs.org root@pbx:~ $ ping www.yahoo.com ping: unknown host www.yahoo.com root@pbx:~ $ ping yahoo.com ping: unknown host yahoo.com root@pbx:~ $ ping microsoft.com ping: unknown host microsoft.com root@pbx:~ $ ping lilug.org ping: unknown host lilug.org root@pbx:~ $ ping centos.org ping: unknown host centos.org root@pbx:~ $
what's a good link to read about how the resolv.conf file is constructed? esp. the "search" entry?
*** This was part of the wget response: www.henrichs.org canonical name = ehost-services119.com. Name: ehost-services119.com Address: 69.64.155.165
Doesn't the "address: Address: 69.64.155.165" indicate a correct result?
*** My nsswitch.conf file does contain: hosts: files dns (this is an interesting file I'll have to revisit...thanks).

It was suggested off-list that I show "the contents of /etc/resolv.conf and a little history on your ifcfg-ethx files in /etc/sysconfig/network-scripts/"
Here is /etc/resolv.conf: root@pbx:/etc/sysconfig/network-scripts $ cat /etc/resolv.conf search isp.com nameserver 216.146.35.35 nameserver 216.146.36.36 nameserver 8.8.8.8 root@pbx:/etc/sysconfig/network-scripts $
Here are the files in my /etc/sysconfig/network-scripts directory: root@pbx:/etc/sysconfig/network-scripts $ ls ifcfg-eth0 ifdown-ippp ifdown-ppp ifup ifup-ib ifup-isdn ifup-routes init.ipv6-global ifcfg-lo ifdown-ipsec ifdown-routes ifup-aliases ifup-ippp ifup-plip ifup-sit net.hotplug ifdown ifdown-ipv6 ifdown-sit ifup-bnep ifup-ipsec ifup-plusb ifup-sl network-functions ifdown-bnep ifdown-isdn ifdown-sl ifup-eth ifup-ipv6 ifup-post ifup-tunnel network-functions-ipv6 ifdown-eth ifdown-post ifdown-tunnel ifup-hdlc ifup-ipx ifup-ppp ifup-wireless root@pbx:/etc/sysconfig/network-scripts $
Here is the contents of the ifcfg-eth0 file: root@pbx:/etc/sysconfig/network-scripts $ cat ifcfg-eth0 # Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ DEVICE=eth0 TYPE=ethernet BOOTPROTO=none BROADCAST=192.168.70.255 IPADDR=192.168.70.40 NETMASK=255.255.255.0 GATEWAY=192.168.70.2 HWADDR=00:1D:7D:26:31:D0 ONBOOT=yes DHCP_HOSTNAME=pbx.local root@pbx:/etc/sysconfig/network-scripts $

I am getting what I believe to be inconsistent replies/results from my CentOs machine, trying to ping URLs. Pinging by URL fails the DNS lookup, while pinging the IP address (that should have been returned) works. The DNS lookup also fails NSLOOKUP, but interestingly, dig and wget return A records with the correct IP.

wget has *not* returned correct IP! Only nslookup and dig.
First try to use only google DNS servers: 8.8.8.8 and 8.8.4.4, and if that does not help, and your only problem is with only that domain, you will have to contact support where domain is parked, and see is that helps.
Only relevant info is in resolve.conf, there is no need to look at network configuration if you can ping IP's.
