I guess I'm stuck: Our ISP is supposed to delegate the zone
176/28.212.8.62.in-addr.arpa
to us, and it appears to be already configured (as far as I can tell
anyway, and that's what their hostmaster tells me) at their end:
----------------------- snip -----------------------

The box under my control is ns.archi-me-des.de, the others are at the
provider's end. My named.conf entry is:
----------------------- snip -----------------------
zone "176/28.212.8.62.IN-ADDR.ARPA" {
type master;
file "28_176.212.8.62.zone";
};
----------------------- snap -----------------------
And the zone file itself is:
----------------------- snip -----------------------
bender:~ # cat /var/named/28_176.212.8.62.zone
$TTL 3600
@ IN SOA ns.archi-me-des.de. frank.joerdens.de. (
2001113003 ; serial YYYYMMDDnn
86400 ; refresh ( 24 hours)
7200 ; retry ( 2 hours)
3600000 ; expire (1000 hours)
172800 ) ; minimum ( 2 days)
;
; nameserver:
;
NS ns.archi-me-des.de.
NS ns2.kkf.net.
NS ns3.kkf.net.
190 PTR ns.archi-me-des.de.
----------------------- snap -----------------------
Which means that, as I understand the mechanism, the IP address
62.8.212.190 should resolve to ns.archi-me-des.de. But it doesn't:
----------------------- snip -----------------------

Can anyone explain? My guess would be that the CNAME entries in the
provider's zone file, like
190 CNAME 190.176/28.212.8.62.in-addr.arpa.
are missing.
Many thanks in advance,
Frank
