Can a DNS record have multiple A records?

Can a DNS record have multiple A records?

You can do a lot with A records, including using multiple A records for the same domain in order to provide redundancy and fallbacks. Additionally, multiple names could point to the same address, in which case each would have its own A record pointing to that same IP address. The DNS A record is specified by RFC 1035.

What happens when you have multiple A records?

Multiple A and AAAA Records The order in which the IP addresses listed above are returned by Google’s name servers is randomized, so different clients will attempt to connect to different IP addresses. If a web browser’s attempt to connect to the first IP address in its list times out, it can try the next IP.

How do multiple DNS A records work?

A DNS server with round-robin enabled will have multiple different A records, each with the same domain name but a different IP address. Each time the DNS server is queried, it sends the IP address to which it most recently responded with to the back of the queue, operating on a loop.

Why are there multiple DNS records?

Multiple DNS records Having more than one name server (a DNS record type) set to your domain name provides redundancy, and works for ensuring your website’s availability at all times.

What is AAAA record DNS?

What is a DNS AAAA record? DNS AAAA records match a domain name to an IPv6 address. DNS AAAA records are exactly like DNS A records, except that they store a domain’s IPv6 address instead of its IPv4 address. IPv6 is the latest version of the Internet Protocol (IP).

Can two DNS records point to same IP?

You can point as many DNS A records to an IP address as you want. In addition, nginx can be configured to listen on different ports, but it will also handle virtual hosts for HTTP so can listen for for different DNS hostnames on the same port.

Can multiple A records point to the same IP?

From DNS point of view, there is nothing wrong with having multiple A records pointing to the same IP. This is often done to “hide” the actual server name, so that application can be moved to a different machine/instance without clients noticing the move.

Can a server have 2 DNS names?

5 Answers. If you want the servers srv and srv-new to point to the same physical machine, you can do this with DNS by just adding another A record in your DNS server. If you wanted to set up two GUIDs for it, that’s not possible.

What is CNAME and Aname?

These are the main differences: The A record maps a name to one or more IP addresses when the IP are known and stable. The CNAME record maps a name to another name. The ALIAS record maps a name to another name, but can coexist with other records on that name.

What are the different types of DNS records?

There are 5 types of DNS records: A, CNAME, NS, MX, and PTR. A records. Address (A) records direct a hostname to a numerical IP address. For example, if you want mycomputer.yourdomain.com to point to your home computer (which is, for example, 192.168.0.3), you would enter a record that looks like:

How can I list all DNS records?

You can view all of the resource records for a given DNS zone by simply using the PowerShell Get-DnsServerResourceRecord cmdlet . Using this cmdlet, you can specify the ZoneName parameter which will list all DNS records in that zone. As you can see below, this generates quite a lengthy list of records.

How do you find DNS records?

To find your domain settings and edit your A record: Log in to your domain registrar and find the DNS management section. In the DNS management section for your registrar, point the A record of your domain name (also denoted as “@”) to the IP address of your website. Check your other DNS records carefully.

Can I point multiple records to a CNAME record?

Pointing a CNAME record to another CNAME record is inefficient because it requires multiple DNS lookups before the domain can be loaded – which slows down the user experience – but it is possible. For example, blog.example.com could have a CNAME record that pointed to www.example.com’s CNAME record, which then pointed to example.com’s A record.
