Just for curiousity, you can change it. /etc/hosts is a link
/etc/hosts -> ../var/tmp/hosts
you can edit but you cannot permanently save it.
cat /etc/hosts
127.0.0.1 localhost
192.168.178.1 fritz.box
217.10.79.8 0.europe.pool.ntp.org ntp.sipgate.de
Now I dont bother pool.ntp.org but ask my sip provider.
That trick might work for the D-Link too.
Of course 0.europe.pool.ntp.org is alright but that
ntp server D-Link has is not.
You have to insert the hostname plus ip into /var/tmp/hosts
or the box will ask DNS.
