- A record (Address Record) - maps URL to IPv4 address
42+
- AAAA record - maps URL to IPv6 address
43+
- CNAME (Canonical Records) - maps URL to URL - use it for non-root domain (Ex: backend.lorem.com)
44+
- Alias - maps URL to an alias (Ex: AWS resource in Route53 - ELB, CloudFront distribution or S3 bucket sites)

- **CIDR** - Classless Inter-Domain Routing - method for allocating a range of IP addresses. CIDR has 2 components:
73+
- *Base IP* (`192.168.0.0`) - represents the first IP contained in the range
74+
- *Subnet mask* (`/24` <=> `255.255.255.0`) - represents how many bits can change in the IP - smaller the subnet mask, the more IPs you'll have in the CIDR range. `/32` allows 1 IP, `/31` allows 2 IPs, `/30` allows 4 IPs, ... `/0` allows all IPs
75+
76+
Ex: `192.168.0.0/24` means you can go from `192.168.0.0 - 192.168.0.255` (256 IPs)
