Can you tell country from IP address?
Yes, if you know the country code. The reverse lookup is of course not possible, so you would have to do a lookup for all addresses in the world. The country code of a domain is a number that is assigned to a domain by ICANN, and is used to determine where in the world a given domain is hosted. For example.com is the root domain for the United States.net for the UK.de for Germany, and so on.
The reverse lookup uses the DNS protocol, which is a distributed database maintained by ICANN, and allows you to query a host you know (eg google.com), and get the IP address for a host you don't know (eg google.de).
The lookup is of course possible, but you would have to query the DNS server for all possible domain names in the world. You can find the root domain for every country here: You could do some simple searching, and find the root domain for a given country.de is for Germany. You could then do
Host -t A google.de in Germany.
There is no way to tell from an IP address. This is because there is no guarantee that the IP address will be within the same network, or even in the same country. The IP is an address that is globally unique.
The domain name is a unique identifier to a particular server or service, which is unique within a network, but globally unique. Therefore, at a later point, you will be able to map a particular domain name to a particular IP address. However, the mapping is not necessarily one-to-one. In fact, it can be many-to-one, or even one-to-many.
How are IP addresses assigned by country?
Below operation is showing no. Of IP addresses by country with respect to human population.
As per census, India has around 2.6 Billion people as of 2022.
The part of the world with the most number of IP address is India. India has 620.93 Million.
Now let's talk about the percentage of IP addresses by country. India has enough numbers to display on the pie chart as of 2022. The percentage of IP addresses for India is 61.52 which is equal to one percent which is the smallest percentage in the world. (Source)
This video shows the beautiful map of the World IP address distribution. IP address or internet protocol address is used to show all the machine connections on the network. IP addresses are assigned to all the computers on a network. It can be retrieved by computer but computer doesn't need it to function.
Currently the world population is 7,54,830,646 people. Let us analyze the number of internet connected people in the world. 1,903,698,173 IP addresses (as of 30th of November 2018). That's a big number, isn't it? 3% of the world's population has internet connection. That itself is a pretty small number, isn't it? 43 countries are having over 95% internet connection. This Indian IP address distribution pie chart is very interesting. India has 0.3% of the world's population but it has 11.5% of the world's IP addresses. Even the portion of IP address by country occupies most of the world's population pie.
What is the reason? There are lots of ways to explain it. So how these IP addresses are distributed? Let's find out. IP addresses Allocation by Country. For better analysis, show the average internet connection by country. As you can see, IP addresses are assigned by country. The explanation of the pie chart can be done in multiple ways. Let there is a country which has internet connection with respect to its population. It makes the country more attractive for the internet.
What is the reason for it? Indian government has put in place a special policy to control internet usage by this country.
What is IP address for India?
An IP address is a 32-bit numerical address that uniquely identifies a host on a network. An IP address is usually a string of four numbers separated by dots, like 10. IP addresses are a key component of the Internet Protocol (IP) suite of networking protocols.
IP addresses are used to route packets of data from one computer to another over the Internet or on a local area network. What is a DNS server? A DNS server is the computer on a network that translates a domain name (hostname) to an IP address. The DNS server also serves as a server of the Domain Name Service (DNS) protocol, which allows you to find the IP address of a hostname, such as www.google.
When you type a domain name into a web browser, the browser sends a request to the DNS server (or servers) to resolve the domain name. The DNS server that receives the request determines the IP address associated with that domain name, and returns it to the browser.
DNS servers are used for two purposes: DNS is the key to finding an IP address for a domain name. DNS is the key to finding an IP address for a hostname, such as www. What is a DHCP server? A DHCP server is a computer on a network that automatically assigns IP addresses to computers on the network. What is a Node? A node is a device or group of devices connected to a network. For example, computers, printers, modems, routers, switches, and other network devices are all nodes.
A node is not necessarily a server, but most servers are connected to the network. What is a subnet mask? A subnet mask is a number that identifies the network that a computer is connected to. The subnet mask is part of the IP address.
For example, if a computer has an IP address of 192.168.1, the subnet mask of that computer would be 255.0, or 24 bits.
The IP address of a computer is made up of two parts: The network address. The host address. The subnet mask identifies the network that the computer is connected to.
