How does it work? You simply put a piece of information in your DNS records that says "for information regarding def.abc.com please ask the DNS server hisdnsserver.def.abc.com.". Of course, to query that server one needs to know the IP-address of hisdnsserver.def.abc.com.. That's what glue records are for.

So let's say you have a DNS server in your office (ns.network.com) and it has a DNS forwarder 8.8.8.8 (this is the public IP address for a Google public DNS server) but you want DNS requests for client.com to go to ns.client.com, then you would create a conditional forwarder that says DNS requests for client.com go to ns.client.com.

2021年3月25日 · I'm also trying to get DNS and http/https running over wireguard for 2 days in a similar setup as you and still failing with name resolution. What exactly do you mean by "register the same dns ... on the main connection as on the wireguard interface".

So to make it work as expected install dnsmasq or other lightweight DNS repeater (or a full blown DNS server). See Comparison of DNS server software. For dnsmasq configuration is as simple as: server=10.0.4.48 server=8.8.8.8 You can also specify which DNS should be used for which domain . E.g.: server=/mcdc/10.0.4.48 server=8.8.8.8

My boss refuses to allow private IP addresses into a public DNS definition. So I am unable to put the private SVN box IP (svn.ourcompany.com) into a .com DNS record. It exists only at svn.ourcompany.local. I don't mind this, ultimately, except when it comes to SSL.

Yeah, much of that is up to the implementation of the DNS tool. You'll see the @ when you work with the DNS files directly, but you'll rarely see it in the various DNS tools. The DNS tools try to simplify the UI. From your messages it sounds like you have it working one way but not another so I recommend going with the way that it does work.

2012年8月1日 · Basically, it's what the name says it is. An authoritative answer comes from a nameserver that is considered authoritative for the domain which it's returning a record for (one of the nameservers in the list for the domain you did a lookup on), and a non-authoritative answer comes from anywhere else (a nameserver not in the list for the domain you did a lookup on).

2019年3月18日 · Ensure port 53 is open to the Google DNS servers via UDP and TCP (it's better to use whatever DNS service is upstream to you rather than Google, by the way). You can use PortQry to check it. On the Forwarders tab, untick the box Use root hints if no forwarders are available. Remember that the dcdiag /test:dns includes a lot of sub-tests. Mine ...

Secondary DNS being geographically and network-separated is a good thing. You might be able to trade secondary DNS with a friendly company, and there's plenty of DNS providers you can pay to do it for you. Some registrars have secondary DNS as a service, too.
