dig working, ping not

I'm a bit lost here. After having pdnsd working for weeks it is acting strange lately.

I can use the DNS from any host on the lan, but not local.

dig www.google.com returns

; <<>> DiG 9.8.1 <<>> www.google.com

but ping www.google.com merely says

ping: unknown host www.google.com

in pdnsd-ctl dump I find

www.google.com.
    01/22 09:24:41    A       (negated)
    01/22 09:24:41    CNAME   www.l.google.com.

/etc/resolv.conf has

# Generated by dhcpcd from eth0
# /etc/resolv.conf.head can replace this line
domain kingma
nameserver 172.16.0.8
# /etc/resolv.conf.tail can replace this line

the pdns host is 172.16.0.8

And from a windows host it works fine:

Default Server:  UnKnown
Address:  172.16.0.8

> www.google.com
Server:  UnKnown
Address:  172.16.0.8

Non-authoritative answer:
Name:    www.l.google.com
Addresses:  173.194.35.16
          173.194.35.18
          173.194.35.17
          173.194.35.20
          173.194.35.19
Aliases:  www.google.com

Re: dig working, ping not

What sort of network card is it and what does

ip route && ip addr

give you?
