Question

1. What is the difference between statically assigned IPs, reserved IPs, self-assigned IPs, and dynamically assigned IPs? Give specific examples of when you would use or see each.

Answer 1

The difference between statically assigned IPs (Internet Protocol), reserved IPs, self-assigned IPs, and dynamically assigned IPs:
* Statically assigned IPs: These IPs or addresses are static, which do not get changed. Fewer devices use statically assigned IP addresses. Most users do not use and need static IP addresses. Static IP addresses would cost users as they are limited.

* Reserved IPs: Some of these IP addresses from the IPv4 pool or address space of 2^32 addresses are reserved for special purposes such as private networks, broadcast, and multicast addressing. These are IP addresses that are non-overlapping ranges of IPv4 addresses been reserved. There are three ranges of these IP addresses. These IP addresses are not routed on the Internet. These IPs are reserved for special, exceptional, and certain purposes. In general, certain and various IP addresses and their ranges are reserved for special or certain purposes. Reserved address space with its range of IPs is reserved and categorized only to be used within internal networks or intranets.

* Self-assigned IPs: These are IP addresses and their three ranges set aside for the computers in local networks, assigned to the machines by a DHCP server on the networks, and these private addresses are not routed over the Internet for security reasons. These IPs are assigned by machines to themselves, with a machine assuming and taking up an IP address to be its.

* Dynamically assigned IPs: These IPs are addresses are dynamic and change with time. More devices use dynamically assigned IP addresses. These IP addresses along with other network configuration parameters are dynamically assigned by a DHCP server and to each one of the devices on a network.
These IP addresses are assigned automatically to each connection, device, node, or a computer on a network. Dynamic IP addresses are free and are virtually unlimited.

Specific examples of when each of them is used or seen:

Examples of dynamically assigned IPs to devices are- smartphones, desktop PCs, printers, wireless tablets, and others.

Example for static IP addresses- These come into the picture more when certain external devices or websites, technically require to track and remember their users' IP addresses. Another example VPN (Virtual Private Network) and other similar remote access applications, products, tools, services, and solutions trusting, whitelisting certain users' IP addresses for security purposes, based on their static IPs. Another example, in case a business hosting a server would use static IPs for their web hosting servers.

An example of one set of reserved IP address range is used by home routers of the users. This is set by default. The range is between 192.168.0.0 and 192.168.0.255, which are Class C IP addresses.
Another IP address range is from 10.0.0.0 to 10.255.255.255, which are Class A IP addresses.
Yet, another IP address range is from 172.16.0.0 to 172.31.255.255, which are Class B IP addresses.
IP address range from 240.0.0.0 to 255.255.255.254 is reserved for future use.
The address range 255.255.255.255 is reserved for the "limited broadcast" destination address.

An example of the usage of a self-assigned IP address to a device on a network is to allow a network interface for creating an ad-hoc network, in case needed in future, without any presence of an already established network.
