Does the order of DNS records matter?
It does not make a difference. All (three) DNS servers have the same information. And the root servers are actually returning the servers in order, only the whois information is showing them in reverse order. Visit Arthur’s homepage!
Which types of DNS records should you use?
Although there are various types of DNS records that all perform different actions, these four record types are the most commonly used.
- A records. What is an A record? Address records, commonly known as host records, resolve IP addresses.
- CNAME records. What is a CNAME record?
- MX records. What is an MX record?
What is the purpose of a DNS A record?
What is a DNS A record? The “A” stands for “address” and this is the most fundamental type of DNS record: it indicates the IP address of a given domain. For example, if you pull the DNS records of cloudflare.com, the A record currently returns an IP address of: 104.17. 210.9.

How is a record used in a DNS server?
A record. The A record is one of the most commonly used record types in any DNS system. An A record is actually an address record, which means it maps a fully qualified domain name (FQDN) to an IP address. For example, an A record is used to point a domain name, such as “google.com”, to the IP address of Google’s hosting server, “74.125.224.147”.
What does a non recursive query in DNS mean?
Non-recursive query – this occurs when a DNS Resolver queries a DNS Name Server for a record, either because the Name Server is authoritative for the record, or the record exists in its cache. DNS servers typically cache DNS records to conserve bandwidth and reduce load on servers further up the hierarchy.
How are DNS records distributed between primary and secondary servers?
DNS servers can be deployed in a primary/secondary topology, where a secondary DNS server holds a read-only copy of the primary DNS server’s DNS records. The primary server holds the primary zone file, and the secondary server constitutes an identical secondary zone; DNS requests are distributed between primary and secondary servers.
When do you need to change a DNS record?
This record is used to delegate a subzone to a set of name servers. These are the types of records you need to modify when you want to delegate a domain to a DNS provider. This record stores important information about the DNS zone (your domain).
