Easy to read and very succinct ! Loved this course. Its better than most other courses  out there that are either half baked or way to detailed. 

Excellent,  time and money well spent on this. 

Richard Guajardo

Got what I was looking for. I used this for my interview prep with AWS. 

Worth it !

Tammy Rogers 

Loved all the architecture diagrams. It really helped in understanding how each service would be used. 

Pretty detailed.

# DNS – basics
DNS is fundamentally used to convert human-friendly domain names to IP addresses. For example, `www.xyz.com` gets translated into `http://18.125.38.x`.

## Domain registrars

As all domains in a top-level domain (i.e. `com`, `.uk`, `.gov`) need to be unique, there needs to be a central authority that owns the assignment and management of domains, this is done by domain registrars.

They essentially register the domain in the central database known as the *WHOIS database*.

**NS Record** stands for Name Server records, they are used by top Level Domain servers to direct traffic to the content DNS Server which holds the authoritative DNS record.

If you register a domain on AWS or `Godaddy.com` you would take your NZ records and give them to GoDaddy that way traffic will be directed to your name server address.

**A – Record**: an ‘A-record’ is the fundamental type of DNS record and the “A” in the record stands for Address. The record is used by a computer to translate the name of the domain to the IP address. 

**TTL (Time to Live)** is the interval length that a DNS record is cached on either the Resolving Server or the user’s own local PC measured in seconds. 
 The lower the TTL the faster the changes to the DNS records propagate throughout the internet.

**C-Name or Canonical Name** is used to resolve one domain name to another. Eg: Resolving `http://m.google.com` to `http://google.com`.  

Alias Records are used to map resource record sets in your hosted zone to elastics load balancers that are configured to your web instances.
