👉 The word "SimpleDns.conf" appears to be a configuration file that defines settings related to DNS (Domain Name System) server setup in a computer or network environment, particularly for use with a simple DNS server configuration using an HTTP client library like OpenSSL.
A Detailed Definition: A SimpleDNS.conf is a configuration file used for a single domain's DNS setup. The conf file is primarily configured for setting up the DNS settings of a single domain, typically containing entries and commands for controlling various DNS service interfaces.
Here are some key aspects of this configuration:
1.
Host File
: This is the first entry in the conf file that defines the hostname and IP address (domain name) to be used by the DNS server. It also specifies the domain's primary and secondary nameservers, if any.
2.
Options
:
- `SOA`: Specifies a service option for the DNS server.
- `SRV`: Enables an SRV record that defines the host records.
- `MX`: Allows multiple lookup domains (multihop).
- `CNAME`: Adds a CNAME alias to point to another domain's IP address.
- `NAPTR`: Specifies the network and subnetwork of the DNS server.
3.
DNS Servers
:
- A single entry for each DNS service interface, such as `AAAA` (Alternative Name Registrar) or `NS`.
- These entries define which DNS server to use for incoming DNS queries.
- You can also create a list of domain names in this section.
4.
Options
:
- `CNAME`: Adds a CNAME alias to point to another domain's IP address, allowing multiple lookups within the same or different domains.
- `SOA` and `SRV` (Service Record) options are used for complex DNS requests that include an external host record.
5.
Hosts
:
- Entries to define the nameservers, secondary servers, MX records, CNAME aliases, etc., for each domain.
6.
Query Options
:
- You can also set query options like `MX` (Multipurpose Internet Mail Extensions), `NS`, and more depending on your specific needs.
7.
Aliases and Nameservers
:
- Aliases are names used to map the IP address of a DNS server to another domain's hostname.
- Nameservers, usually configured as a list, define which domains to forward DNS queries for.
8.
DNS Server Configuration
:
- This section defines how the DNS server is set up, including the DNS servers, key files, and other configuration settings.
The purpose of this configuration is to ensure that a single domain's DNS settings are managed by one central point, improving scalability, performance, and security when multiple domains share the same server.
