What DNS record is used to identify an IPv6 host?
The DNS record used to identify an IPv6 host is the AAAA (pronounced "quad-A") record. It maps a domain name to its corresponding IPv6 address, allowing clients to resolve the domain to an IPv6 address for network communication. This is similar to how A records are used for IPv4 addresses.
What is an IPv6 DNS host record is referred to as?
The IPv6 host record is referred to as a AAAA record.
How does the HOST file relate to DNS?
The host file provides a list of static DNS entries for a specific computer. In general, the computer checks it's host file for DNS lookup before going to the DNS server.If the server name is found in the host file, the computer uses the specified IP address. Otherwise, the server queries a DNS server for name lookup.
What should you check if you can connect using the IP address but NOT with he host name?
DNS
Which mechanisms could you use to resolve a host name into its associated IP address?
A DNS is used to convert Host Names into IPs and IPs into host names. (DNS = Domain Name Server).
What type of DNS zone is used to resolve and IP address to a host name?
The type of DNS zone used to resolve an IP address to a host name is called a Reverse DNS zone. This zone uses PTR (Pointer) records to map an IP address back to its corresponding domain name. Reverse DNS lookups are often used for logging, verification, and security purposes.
When a DNS server resolves a host name to an IP address what is the process called?
Name resolution
What command should you enter to view the host name and dns server address?
ipconfig / all
How exactly does DNS PTR work?
PTR is an abbreviation for pointer record. This pointer record is often used to do a reverse DNS search. DNS means DOMAIN NAME SYSTEM. These searches are done in order to figure out someone's IP address.
What kind of DNS record is likely to be returned when a Web browser tries to resolve the domain part of a URI?
An A (address) record
What is DNS doctoring?
DNS doctoring enables an internal host on a LAN to receive the Private ip of an internal server as an answer from a DNS query when using a DNS server that is outside the LAN, such as on the internet. A static NAT translation must also exist to translate the public IP to the private IP. Without DNS doctoring, the external DNS server will reply with the public IP address of the host on the internal LAN.
Reverse look up by address?
Let's say you type in the host name, "www.google.com" into your browser. The browser will contact the DNS (Domain Name Server) and ask it for the ip address (192.117.0.1 for example) for www.google.com. This is what's called a forward lookup. The reverse lookup then is when the browser has the ip address but needs to find the host name for that address. So the browser contacts the DNS using the ip address and asks for the host name.
