Abstract
- Human-readable names given to the Host
- Domain Name, Canonical Hostname (CNAME) and Alias Hostname are all considered as hostname
Limitation
- Doesn’t contain enough information to locate the Host on the Internet
- Difficult to be processed by Network Router
Solution
Create a mapping between hostname and IP Address using DNS. IP Address is capable of solving the limitation of hostname but not human-readable which is mitigated by DNS
Canonical Hostname (CNAME)
- A less readable Hostname
- For example, my blog CNAME is
d29nyp1p0lllzw.cloudfront.net
Alias Hostname
- A more readable Hostname, usually aliasing to Canonical Hostname (CNAME) or IP Address
Domain Name
- Examples are
notes.yxy.ninjaandgoogle.cometc
Domain Name Transfer
Transferring from one Domain Registrar to another. The general steps:
- Disable DNSSEC
- Unlock Domain
- Request an authorization code, also known as EPP Code
- Initiate transfer to the new Registrar with the EPP Code
- The old registrar sends a transfer confirmation email, confirm it
Refer to Cloudflare Docs for more details
