7. What challenges arise regarding the uniqueness of IP addresses across the entire internet, and how are private networks and Network Address Translation (NAT) involved?
If a host is connected to multiple subnets, it has at least one IP address per subnet. Each host's IP address should be unique across the entire internet, when going into more details, private networks and Network Adrress translatin makes it confusing.
Each host connected to the internet must have a unique IP address to ensure proper communication. Ensuring unique IP addresses for each internet-connected host is challenging due to limited IPv4 availability. Private networks use reserved ranges, and for internet access, Network Address Translation (NAT) lets multiple devices share a single public IP. This can cause confusion, as externally, multiple hosts in different private networks may appear to share the same public IP address.
