    Hello there, everyone!

    I'm a layman trying my best to understand what I'm reading when it comes to this, so please go easy. I have managed to resolve my ERRORs and am now left with just a few warnings that I can't figure out how to resolve.

    My server is hosted at:
    I host the domain at and use their nameservers to provide A records pointing to my server.

    dns Local NS list does not match Parent NS list
    dns Name Servers are on the Same Subnet
    dns SOA Expire Value out of recommended range

    Can someone tell me if these can be resolved with my hosting setup and if so, how I would go about it?

    Thanks for your time!

    The nameservers defined in the zone are not the same as registered for the domain. Determine which is correct, then set the other to same values.
    Ignore this, unless you have another location where you can run the second name server.
    Set the TTL to recommended value, I do not remember what it is but wikipedia probably knows.

    Thanks for the help!
    I've not defined any nameservers in my ISPConfig install. Is that what I need to do to resolve this issue?

    You said you are using the DNS servers of your provider, in that case, do not add a zone for this domain in ISPConfig.

    Then is this a warning that I cannot resolve in the way that the domain pointing is handled

    the ns servers should be and, they should be set at NS records in your dns zone on (assuming ns1 and ns2 are the correct nameservers used by

    for the SOA TTL settings.. i use the following, which tests show as within the recommended range..
    Refresh 7200 Seconds
    Retry 540 Seconds
    Expire 1029600 Seconds
    Minimum (negative cache ttl) 86400 Seconds
    TTL 3600 Seconds

    the defaults set by's dns servers should already be within the recommended ranges.

    when looking at the 101domain panel, it seems the only value I have the ability to change is TTL. It looks like I'm unable to modify anything else.

    As far as I understand it, everything works, you have just a few warnings where an external DNS tester complains about the setup of DNS servers at your hosting provider, right? In that case, just ignore the warnings. You probably can't change it anyways.

    I tested with that domain. The reason it complains is parent domain has three name servers, zone defines only two. If you want to get rid of the warning make them match (i.e. add the third name server to zone).
    Where did you get the warnings you wrote about in #1? Did it not tell the reason like
