Jim,
If they were filtering icmp wouldn't it also block the pings by ip address?

Almost sounds like ICMP is blocked at a firewall or maybe a filter on the
IBM i.

This may sound like the same post as before, but it's not. :)

I have a client who can ping IP addresses from their IBM i (like

8.8.8.8)

but not host names (like google.com)

It just hangs when pinging a host name vs an IP address which returns
expected results.

They do have 8.8.8.8 and 8.8.4.4 set up as their DNS servers. No host
table entries set up that should cause any problems.

Any ideas what this could be?
