What is zone Apex record?
A zone apex record is a DNS record at the root of a DNS zone, such as ‘example.com. ‘ RFC 1034 states that the zone apex must be an A Record, and not a CNAME record. This means that the zone apex record must point to one or more IP addresses. With many AWS services, a DNS name is provided rather than IP addresses.
Does Route 53 support zone apex records?
Yes. Amazon Route 53 offers a special type of record called an ‘Alias’ record that lets you map your zone apex (example.com) DNS name to your Amazon CloudFront distribution (for example, d123.cloudfront.net).
What is the apex zone called?
The apex (sometimes known as the zone apex or domain apex) refers to records where the record name is the same as the zone’s domain name. In the zone for example.com, a record for example.com is said to be at the zone apex.
What is zone record in domain?
A zone file contains mappings between domain names, IP addresses and other resources, organized in the form of resource records (RR). To see the actual zone file for a domain, and test DNS zone transfers, you can perform a zone file lookup using one of many DNS tools.
Who is DNS record?
A DNS record is a database record used to map a URL to an IP address. DNS records are stored in DNS servers and work to help users connect their websites to the outside world. When the URL is entered and searched in the browser, that URL is forwarded to the DNS servers and then directed to the specific Web server.
What is zone Apex mapping?
Zone apex mapping uses the mapping data available on the Akamai platform to reduce DNS lookup times for your websites. With zone apex mapping, name servers resolve DNS lookup requests with the IP address of an optimal edge server.
Does Amazon Route 53 support NS records?
Does Amazon Route 53 support NS Records? Yes, it supports Name Service records.
What is DNS NS record?
An NS record (or nameserver record) is a DNS record that contains the name of the authoritative name server within a domain or DNS zone. When a client queries for an IP address, it can find the IP address of their intended destination from an NS record via a DNS lookup.
What are AAAA records used for?
Like A records, AAAA records enable client devices to learn the IP address for a domain name. The client device can then connect with and load the website. AAAA records are only used when a domain has an IPv6 address in addition to an IPv4 address, and when the client device in question is configured to use IPv6.
What are 3 types of DNS records?
3 types of DNS queries—recursive, iterative, and non-recursive.
What are the 3 types of DNS zones?
Types of DNS Zones
- Primary zone.
- Secondary zone.
- Active Directory-integrated zone.
- Stub zone.
- Reverse lookup zone.
What are the 3 types of DNS?
There are three main kinds of DNS Servers — primary servers, secondary servers, and caching servers.
- Primary Server. The primary server is the authoritative server for the zone.
- Secondary Servers. Secondary servers are backup DNS Servers.
- Caching Servers.
Why is Amazon called Route 53?
AWS Route 53 takes its name with reference to Port 53, which handles DNS for both the TCP and UDP traffic requests; the term Route may signify the routing, or perhaps the popular highway naming convention.
What is NS record in AWS?
The name server (NS) record
Amazon Route 53 automatically creates a name server (NS) record that has the same name as your hosted zone. It lists the four name servers that are the authoritative name servers for your hosted zone.
Why do we need NS record?
This allows you to change web hosts without changing domain names. Each website has a specific IP address, and the DNS records pair that IP address to the domain name so users don’t need to remember the numeric line. DNS records hold information about every single website on the internet.
What is difference between A record and NS record?
NS record VS A record
As we already mentioned above, NS records delegate the DNS zone to use the given authoritative name servers. The purpose of the A record is quite different. The A record is used for a Forward DNS resolution. In short, the A record points your domain to your server.
What is a VS AAAA?
A and AAAA records are equally important when it comes to resolving DNS. The difference lies in that A records is used to resolve a hostname which corresponds to an IPv4 address, while AAAA records are used to resolve a domain name which corresponds to an IPv6 address.
Is AAAA record necessary?
No, it is not necessary to create an AAAA record for your website as long as most traffic runs over IPv4, but I would argue that it probably is beneficial for the deployment of IPv6 to have more sites support the protocol.
What are 4 DNS records?
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 are the 4 DNS servers?
In all, there are four different DNS servers involved in loading a webpage (assuming it’s not already cached on the user’s computer or device):
…
How Does DNS Work?
- DNS recursor.
- Root nameserver.
- TLD nameserver.
- Authoritative nameserver.
How many zones are in DNS?
There are two types of DNS zones – Primary (Master) DNS zone for control and Secondary (Slave) DNS zone for redundancy and better performance. The first contains all the original DNS records, and the second gets them from the Primary DNS zone. The process is called DNS zone transfer.
What is DNS zone example?
DNS zones are not necessarily physically separated from one another, zones are strictly used for delegating control. For example, imagine a hypothetical zone for the cloudflare.com domain and three of its subdomains: support.cloudflare.com, community.cloudflare.com, and blog.cloudflare.com.
What is AAAA DNS record?
An AAAA record is used to find the IP address of a computer connected to the internet from a name. The AAAA record is conceptually similar to the A record, but it allows you to specify the IPv6 address of the server, rather than the IPv4.
What DNS does Amazon use?
