Add A, AAAA and PTR records to the DNS. This adds one or more names to the DNS with associated IPv4 (A) and IPv6 (AAAA) records. A name may appear in more than one --host-record and therefore be assigned more than one address. Only the first address creates a PTR record linking the address to the name. This is the same rule as is used reading hosts-files # The following line shows how to make dnsmasq serve an arbitrary PTR # record. This is useful for DNS-SD.

So dnsmasq has enough support (ptr, ttl, mx) for being authoritative. One cannot set ttl for each record but this is rarely necessary. It even works without ns, it's just inelegant to have no answer when asking to the machine responsible for the zone. While dnsmasq doesn't generate NS records, I should think it would forward the query to the upstream nameserver, which would recurse and. As specified in the manpage of dnsmasq option--auth-zone=<domain>[,<subnet>[/<prefix length>] allows to : Define a DNS zone for which dnsmasq acts as authoritative server. Locally defined DNS records which are in the domain will be served. If subnet(s) are given, A and AAAA records must be in one of the specified subnets By default, dnsmasq service read /etc/hosts to resolve a hostname. Therefore, in order to add records to your DNS server running dnsmasq, you just need to add records /etc/hosts in the DNS server as below. # cat /etc/hosts 127.0.0.1 localhost 10.10.10.10 dnstest.com After that, restart dnsmasq service
2、Dnsmasq的主要作用. （1）将Dnsmasq作为本地DNS服务器使用，直接修改电脑的本地DNS的IP地址即可。. （2）应对ISP的DNS劫持（反DNS劫持），输入一个不存在的域名，正常的情况下浏览器是显示无法连接，DNS劫持会跳转到一个广告页面。. 先随便nslookup 一个不存在的域名，看看ISP商劫持的IP地址。. （3）智能DNS加快解析速度，打开/etc/dnsmasq.conf文件，server=后面可以添加指定的DNS. Then set these DNS records on your registar panel: 1 2 3 4. A yourdomain.tld 10.20.30.40 AAAA yourdomain.tld ip:v6::ad::dr:ess NS ns1.yourdomain.tld 10.20.30.40 NS ns2.yourdomain.tld 10.20.30.40. please take note that you sould have two different dns servers in case the first goes down The dnsmasq man page says:--host-record=<name>[,<name>.][<IPv4-address>],[<IPv6-address>] Add A, AAAA and PTR records to the DNS. This adds one or more names to the DNS with associated IPv4 (A) and IPv6 (AAAA) records. A name may appear in more than one host-record and therefore be assigned more than one address. Only the first address creates a PTR record linking the address to the name. dnsmasq --ptr-record Copy --naptr-record Return an NAPTR DNS record, as specified in RFC3403. dnsmasq --naptr-record Copy --cname Return a CNAME record which indicates that <cname> is really <target>. There are significant limitations on the target; itmust be a DNS name which is known to dnsmasq from /etc/hosts (or additional hosts files), from DHCP, from --interface-name orfrom.
Dnsmasq is made from three subsystems: DNS subsystem : It is used for caching different records type including, A, AAAA, CNAME and PTR. DHCP subsystem : It supports DHCPv4, DHCPv6, BOOTP and PXE; Router Advertisement subsystem : It provides basic autoconfiguration for IPv6 hosts. It can be used stand-alone or in conjunction with DHCPv6 The following line shows how to make dnsmasq serve an arbitrary PTR. record. This is useful for DNS-SD.

I'm using dnsmasq 2.68. It's mostly working, however I'm having a few troubles with PTR records when using auth-zone and auth-server. If I use these options, then: * PTR look-up of IP addresses defined by interface-name=example.lan,br0 return an answer, but the returned status is NXDOMAIN rather than NOERROR. * No custom PTR records can be defined with ptr-record. If I remove the auth-zone and. Dnsmasq can be configured to add various types of records like SRV, PTR, and NAPTR to its internal DNS server by various directives in its configuration file. But what if there's a less common type of DNS record that you want to serve, which dnsmasq doesn't have a specific configuration directive to handle? Handily, dnsmasq also supports serving arbitrary DNS resource records using the dns. If this option is set, Dnsmasq will not forward reverse DNS lookups (PTR) for private addresses (RFC 1918) to upstream name servers. Any entries in the Domain Overrides section forwarding private n.n.n.in-addr.arpa names to a specific server are still forwarded. If the IP to name is not known from /etc/hosts, DHCP or a specific domain override then a not found answer is immediately. # The following line shows how to make dnsmasq serve an arbitrary PTR # record. This is useful for DNS-SD. (Note that the # domain-name expansion done for SRV records _does_not # occur for PTR records.) #ptr-record=_http._tcp.dns-sd-services,New Employee Page._http._tcp.dns-sd-services # Change the following lines to enable dnsmasq to serve TXT records. # These are used for things like SPF. The dnsmasq man page says:--host-record=<name>[,<name>.][<IPv4-address>],[<IPv6-address>] Add A, AAAA and PTR records to the DNS. This adds one or more names to the DNS with associated IPv4 (A) and IPv6 (AAAA) records. A name may appear in more than one host-record and therefore be assigned more than one address. Only the first address creates a PTR record linking the address to the name.
Only the first address creates a PTR record linking the address to the name. This is the same rule as is used reading hosts-files. host-record options are considered to be read before host-files, so a name appearing there inhibits PTR-record creation if it appears in hosts-file also. Unlike hosts-files, names are not expanded, even when expand-hosts is in effect. Short and long names may. Die Manpage zu dnsmasq sagt:--host-record = <Name> [, <Name>.] [<IPv4-Adresse>], [<IPv6-Adresse>] Fügen Sie dem DNS A-, AAAA- und PTR-Einträge hinzu. Dadurch werden dem DNS ein oder mehrere Namen mit zugehörigen IPv4- (A) und IPv6- (AAAA) Einträgen hinzugefügt. Ein Name kann in mehr als einem Host-Datensatz vorkommen und daher mehr als einer Adresse zugewiesen werden. Nur die erste.
If you use dnsmasq, you can interfere in a number of ways to get a forward lookup going to 127.0.0.1 and the reverse lookup from 127.0.0.1 going to your host. For example, if your hostname is host1.mydomain.com with a real IP address of 192.168.1.12, then you can get 127.0.0.1 to resolve to it by doing the following in the dnsmasq configuration file: host-record=host1.mydomain.com,127...1. IPv6 to to PTR Record. This tool will generate an PTRv6 record for DNS Servers like BIND from an IPv6 address using the nibble format.

Reverse DNS Tool Lookup the Hostname (PTR Record) for an IPv4 Address, IPv6 Address or Hostname Add a new PTR record. For the name, enter the final digit of the IP address that you're setting up the reverse record for. EX: 100. For the Canonical Hostname, enter the domain you'd like the IP address to resolve. EX: mailserver.example.com. After you've saved your file zone, allow time for the change before validating the new reverse DNS.

In /etc/dnsmasq.d/dns we set dnsmasq to always record the Fully Qualified Domain Name (FQDN) in its lookup tables. Resource Records are the basic information element of the DNS, and PTR records are for querying the DNS server with an IP address and getting back the name (called reverse lookup), which dnsmasq does automagically, saving us some work - we have to do this by hand for. Create PTR records for IPv4 and IPv6 addresses. A pointer (PTR) record translates an IP address to its domain name. IPv4 PTR records are represented by the octets of an IP address in reverse order with the string in-addr.arpa. appended at the end. For example, the PTR record for the IP address 1.2.3.4 is 4.3.2.1.in-addr.arpa PTR resource records associate an IP address with a computer name. This entry is designed for enterprises where the primary DNS server that is authoritative for the reverse lookup zone can't, or is configured not to, perform DNS updates. It reduces unnecessary network traffic and prevents event log errors that record unsuccessful tries to register PTR resource records.

Linking a domain name to an IP of a server is called forward resolution and involves referring to DNS records called pointer records. These PTR records can also do the reverse: in other words, reverse lookup or reverse DNS lookup. There is a specific PTR record, called the name portion, which stores entries that.

The DNS subsystem provides a local DNS server for the network, with forwarding of all query types to upstream recursive DNS servers and caching of common record types (A, AAAA, CNAME and PTR, also DNSKEY and DS when DNSSEC is enabled) Then add PTR records for all of your servers whose IP addresses are on the subnet of the zone file that you are editing. In our example, this includes all of our hosts because they are all on the 10.128../16 subnet It does work here with a caveat; after editing /etc/hosts, restart DNSMasq. /tmp/hosts gets recreated on boot. To make this fix persistent, write a startup script to add the new records in /tmp/hosts. Since the startup script will run after dnsmasq starts, you also need to notify dnsmasq to reload. For example, if you populate your /etc/hosts with the startup_rc script like: echo '192.168.1.50. # This option only affects forwarding, SRV records originating for # dnsmasq (via srv-host= lines) are not suppressed by it. #filterwin2k # Change this line if you want dns to get its upstream servers from # somewhere other that /etc/resolv.conf #resolv-file= # By default, dnsmasq will send queries to any of the upstream # servers it knows about and tries to favour servers to are known # to be.
