I do not get it.
I need to update the DNS zone sokoll.com

On the name server (​ #bind​ )

allinclusive:/var/lib/named/master # grep vpn sokoll.com
ssh IN CNAME vpn
vpn IN A 91.66.58.118
vpn IN AAAA 2001:470:6d:c40:210:75ff:fe1a:c7cf
allinclusive:/var/lib/named/master #

Zone is up to date:

allinclusive:/var/lib/named/master # rndc reload sokoll.com
zone reload up-to-date
allinclusive:/var/lib/named/master #

Looks good:

allinclusive:/var/lib/named/master # rndc zonestatus sokoll.com
name: sokoll.com
type: master

allinclusive:/var/lib/named/master #

But:
```
~$ host vpn.sokoll.com ns.sokoll.com.
Using domain server:
Name: ns.sokoll.com.
Address: 195.110.60.28#53
Aliases:

vpn.sokoll.com has address 91.66.45.77
vpn.sokoll.com has IPv6 address 2001:470:6d:c40:210:75ff:fe1a:c7cf
~$
``
91.66.45.77` is an old address that I need to replace.
I must be blind :-/
