Odd… perhaps post what you have in /etc/nsswitch.conf ? Otherwise,
I’m not sure off the top of my head. What does pinging by DNS name work
(vs. just host name)? Also, I assume you’re NOT pinging from either DNS
server.

Good luck.

Bad choice. The .local TLD is handled specially by many systems,
including SUSE.

If cjcox' solution works for you, fine. But I'd still recommend
staying away from .local domain names.

What is the story on multicast DNS and the .LOCAL TLD anyway?
