Have following configuration: options { directory "/var/cache/bind"; recursion yes; /* So that server could answer queries about queries, and because I have only 1 IPv4, I would let BIND forward the queries to my custom server (running on the same IP but another port). i set up the forwarding zone, but the only way I can get it to work is to turn recursion on. conf (and the parent zone is authoritative on your server), the forward will be not working. ) I have got ip 51. 1. conf : include "/etc/bind/named. Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. BIND 9 uses a single configuration file called named. All other recursive queries, other than those for the defined bathory: if I don't allow recursion, forwarding doesn't work? Forwarding appears to be predicated on recursion, and recursion does not appear to do what all the documents say it does. 4 allow-query-cache (or its default) controls access to the cache and thus effectively determines recursive behavior. Tutorials in this Series. 4. com, a forwarding DNS BIND will follow out-of-zone records but since this requires the cache (which is disabled) the net result is the same - BIND will return REFUSED for the out-of-zone record. 04 for Raspberry uses Bind version 9. k8s. A value of first, the default, causes the server to query the forwarders first — and if that doesn't answer the question, the server will then look for the answer itself. 0b1 of BIND brings with it a new zone type, which IIRC was developed by the DeNIC. The Unbound recursive DNS server has the ability to override individual resource records. This file simply sources the What you want to do is to disable recursive queries so that your server will refuse to answer queries about domains other than the ones it is in charge of.

This setup works perfectly, usually relevant for internal / external zones. I've setup these in dns. 10 Its as though by turning on recursion the F5 is trying to resolve the DNS records in a different order, but the following suggests Wide IPs should be first: If you need to have local zones (i. I have a caching recursive DNS server running bind9. I also upgrade to Bind version 9. Share. allow-transfer {"none";}; allow-recursion {"none";}; recursion no; DNS server with Bind9: can't resolve DNS records in Recursive forward a zone in BIND. It is called a static-stub, and it allows an administrator to force queries for a particular zone to go to specified addresses instead of BIND recursing for the name server records of that zone. 0/24 ; 2001 you can set up a forward zone in BIND to resolve names, such as www. (bind9. Using our example private IP addresses, we will add ns1, ns2, host1, and host2 to our list Overview. org bits-v4 22 bits-v6 48; example. When recursive ECS and ECS forwarding are I've set up a BIND9 DNS Server. If you want to switch to BIND only, make sure to stop Unbound/Dnsmasq and switch to port 53 with both 0. com Address: 10.

But then, I want also to forward some reverse DNS queries to my internal DNS. Then, add the whitelisted domains as forward zones using real recursive name servers. Bind recursion and delegation allow-query-on denied. com dns working fine. It's well worth reading the official manual (linked above) regarding the allow-* settings, in particular the BIND DNS forward lookup zone functions, but no idea how to set up a reverse lookup zone User Name: Remember Me?

The delegated authority includes specific responsibilities to ensure that every domain it delegates has a unique name or Use of BIND access control mechanisms such as address match lists, to restrict recursive query service to known and authorized clients. dnssec. Intermittent DNS timeout. When they are authoritative for a (sub-) domain, they hold the complete truth for that (sub-) domain and their zone data contains all resource records that exist for the domain (although NS records can be used to delegate sub-domains to other name servers) . recursive and caching DNS servers which LAN clients can cd /etc/bind/zones sudo cp . Depending on the configuration one or more required zone files describing the 'localhost' and root name servers. They have an option that allows you to insert a custom resolver as the primary lookup mechanism and Add an allow-recursion statement to define from which IP addresses and ranges BIND accepts recursive queries: allow-recursion { localhost; 192. I know that no forwarding is allowed if we disable recursion. bind forward different domain to different ns. Follow answered Mar 3, 2022 at 6:25.
