Can NS record be an IP address?
Every DNS server from a DNS zone must have a dedicated NS record assigned to it. However, the role of NS records are limited because they only serve to define the name of the domain name servers inside a zone, NS records don’t include the IP addresses that will make sure that a domain resolution request succeeds.
Why is a record important for a domain name?
A record holds the IPv4 address of a domain and is the most important of these records. One domain or sub-domain can have a single IP while one IP can have multiple domains pointing to it. AAAA record is essentially the same as A record but for IPv6 addresses.
Does an A record have to be an IP address?
210.9. A records only hold IPv4 addresses. If a website has an IPv6 address, it will instead use an “AAAA” record. The “@” symbol in this example indicates that this is a record for the root domain, and the “14400” value is the TTL (time to live), listed in seconds.
What is the difference between domain name and IP address?
An Internet Protocol, or IP, address is different than a domain name. The IP address is an actual set of numerical instructions. The domain name functions as a link to the IP address. Links do not contain actual information, but they do point to the place where the IP address information resides.
What is the difference between NS and DNS?
NS, or Name Server records, are the top-most records attached to your domain. While DNS (or Domain Name System) records are also public, they are only stored in one specific location. The NS record then responds and tells your computer, “You’ll find the DNS records for that domain on “X” server.”
What is a NS record example?
A DNS Name Server (NS) record specifies the domain name of the name server servicing a particular domain. For example, an NS record with a time-to-live (TTL) of 1100 seconds, and for the com domain serviced by the name server a.gtld-servers.net , would be defined as below: 1100 IN NS a.gtld-servers.net.
What are NS records for a Domain Name System?
The NS records for a domain are the DNS servers that are the ultimate authority for that domain. It’ll be the one that you change when you need to change an IP address for your system. Since DNS servers keep a cache of the information they’ve gotten, the DNS a client reads your information from is not necessarily yours.
What’s the difference between a and NS in DNS?
The NS records specify the servers which are providing DNS services for that domain name. The A records point host names (such as www, ftp, mail) to one or more IP addresses. It is important to have both NS and A record in zone if you need to delegate sub-zone to different DNS server.
Can a DNS record tell which IP address belongs to a sub domain?
But as I understood, the NS record tells which nameserver points belongs to a (sub) domain, and that nameserver should tell which IP-address belongs to a (sub) domain. But that was already specified in the A record in the same DNS file.
What’s the difference between a and NS records?
The NS records specify the servers which are providing DNS services for that domain name. The A records point host names (such as www, ftp, mail) to one or more IP addresses. NS records exist SOLELY for the purpose of defining WHICH NAMESERVERS are responsible for a particular domain.
