This article discusses DNS records of the NS and SOA types in detail. For general instructions on DNS records and how to set them up in the customer administration, see DNS - Domain Records.
In this article you will learn:
NS type records
NS records are commonly used to provide a list of authoritative DNS servers for a domain or subdomain.
WEDOS supports NS records only for subdomains. To set up DNS servers for the main domain, follow the Domains - DNS Servers (NSSET) instructions.
Entering NS type records
For general instructions on DNS records and how to set them up in the customer administration, see DNS - Domain Records.
Before you set up NS records according to the service provider's instructions, consider that WEDOS supports NS records only for subdomains. To change authoritative DNS servers, follow the instructions in Domains - Change DNS Servers (NSSET).
Follow these rules when completing an NS record:
- Do not leave the name field blank, fill in the subdomain name (without the main domain name).
- Enter the DNS server address in the form of a domain, not an IP address.
- Provide a separate record for each authoritative DNS server address.
A general NS type record looks like this:
Name TTL Type Data (subdomain name) 300 NS (DNS server address)
SOA record type
A SOA (Start Of Authority record) is a special record that must occur once in each zone file. It is a kind of header that contains the following information:
- MNAME - the name of the primary DNS server for the zone
- RNAME - contact for the zone file administrator (email address with a period instead of the @ sign)
- SERIAL - zone serial number (a numeric value indicating the version of the zone file)
- REFRESH - number of seconds between serial number checks
- RETRY - number of seconds for the next attempt to find the serial number if the previous attempt failed
- EXPIRE - the number of seconds after which the zone whose serial number could not be found expires (the secondary DNS server should exclude it from its records)
- MINIMUM - currently the TTL for negative caching (the time it takes for the caching DNS servers to remember that a record does not exist)
Setting the SOA record type
The WEDOS administration does not support SOA type record, the system sets it automatically within the DNS servers (NSSET) settings.
Frequently Asked Questions
My service provider wants me to enter the NS records of the domain, but WEDOS only allows this for subdomains. What should I do?
You can set up the necessary records by changing the DNS servers (NSSET) of the domain according to this guide.
Where can I find the values of the information contained in my domain's SOA record?
