    This depends on the /etc/hosts file. the /etc/hosts file should contain the internal IP addresses and not the external ones to ensure that connections are made trough the internal network.

    If the servers are behind a NAT router, then you use the internal IP there. If the servers have two networks, an internal and external network, and no NAT is used, then you use the external IP there.

    I start that topic because I wanted to change the IP of one of my multiserver conf.
    During that change, first thing I did was to change all my DNS.
    Unfortunatelly one of them refused to sign...
    I did so many things to try to solve : update many times, check and validate all DNS record, modify slightly zone, etc... Nothing appeared in syslog...
    Finally, after running `rndc reload`, I found in syslog : (I change IP number by OLD IP : it is the IP of my previous server)
    /var/log/syslog:Apr 11 21:20:36 ns1 named[2003475]: client @0x7f0arqgcd5e0 OLD_IP#59052 (mydom.fr): query (cache) 'mydom.fr/DNSKEY/IN' denied

    I don't find out how to solve that ?
    Currently, I removed signature. But I would like to come back to DNSSEC signed DNS !

    Any idea ?

    This issue makes my DNS instable...
    Code:
    Network Error (dns_server_failure)

Your request could not be processed because an error occurred contacting the DNS server.
The DNS server may be temporarily unavailable, or there could be a network problem.

Transaction ID: a0f03a54a25469b1-000000008f298fb3-0000000062552aca

For assistance, contact your network support team.
    Any idea to help ?

    Hello,
    It kills my access...
    So I remove DNSSEC from 2 domains concerned by that issue.

    How can I restart DNSSEC signing process after doing it once ?
    In other words, I uncheck "sign zone (DNSSEC)" in DNS > Zone > mydom
    I would like to reset DS record in below frame and fully recreate a new one
