■ What is DNS?
Domain Name System (DNS) was created by Paul Mockapetries in 1983. The system allowed the Internet users to access
websites more easily through DNS servers rather than memorizing lots of complicated numbers. For example,
Net-Chinese’s website URL is www.net-chinese.com.tw, and by typing this URL into your browser’s URL bar, you’ll be
directed to a server with an IP address 220.127.116.11.
Due to some limits, DNS is often attacked by hackers. To enhance the security level, DNSSEC (DNS security extension
standard) is invented. DNSSEC can be deemed as an add-on for DNS. It uses digital signatures to avoid problems such as
DNS data being changed by hackers.
■ Common DNS record types
Below are some common DNS record types:
► A record：this is the most common and the most important record type; it is used to map a hostname to an IPv4 address.
► AAAA record：similar to A record, but AAAA requires an IPv6 address instead of IPv4.
► CNAME record：it is an alias of one name to another. It can be used to be pointed to A record, but shouldn’t be used
for another CNAME record.
► TXT record：this is often used for machine-readable data such as a host/ Internet environment’s settings.
► MX record：this is to specify the email server associated with the domain name.
Above settings are all available at Net-Chinese, and we provide up to 50 free DNS records for our clients.
