Nowadays, various devices are consistently manufactured with different modifications to make access to internet services more accessible and faster. These devices can be used to access internet services via the Internet Service Provider (ISP). An Internet Service Providers have unique digits assigned to each device that is connected to them. These unique digits are known as Internet Protocol. The internet protocol (IP) is a unique digit that is designated to a device that is used to connect to an internet service provider. This code is unique to only one device. This means that all devices that are connected to the same internet service provider get different IP addresses. The IP address is essential for security and other vital purposes. With the IP address, you can checkmate any fraud attempt from the customer. It also assists companies in identifying the location of your device and redirect internet service to the nearest server to decrease latency and increase internet speed. To detect the IP address of any device connected to an internet service provider, you need an IP checker. Today, I will be sharing with you all you need to know about the IP address lookup.

IP address lookup is a way of detecting the information about an IP address. It is also called IP checker or IP lookup. With the IP address lookup, you can obtain detailed information about various IPs which includes IPv4 and IPv6. You can also use the IP address lookup tool to acquire information about the Internet Service Provider, geolocation data, timezone, ASN, risk analysis report, and hostname. The IP address is also analyzed to obtain information like VPN, proxy, or TOR connection. Furthermore, when IP address lookup is performed on the IP address of a device, the American Registry for Internet Number (ARIN) is queried and tested. The query sent to ARIN is then answered by a domain, IP database server, or passive DSN. Many a time, the information obtained from the IP address lookup is useful to system administrators, technical users, security researchers, DNS attackers, and spammers.

Way of Performing IP Address Lookup

Carrying out an IP address check is inevitable when its importance is considered. Hence, there is a need to discuss the tools that can be used to perform the technical check. You can either use the w eb-based services or terminal-based commands. The IP address check can be performed with computer operating systems like Linux, Windows, and Unix. However, it has been discovered that the Linux operating system is one of the most efficient operating systems that can be used to perform the IP address check.Here, I will take a look at how you can perform an IP address lookup.

3. nslookup

nslookup is an excellent network administration terminal-based tool that can be used to run system administration and network diagnosis check.

4. Ping

Ping is a terminal-based command that is used to determine if a device or network is online. This is determined when the device responds to the request of the remote network. The Ping command performs the check by using the Internet Control Message Protocol (ICMP) echo to send a packet to a specific network through its network. As soon as the packet is seen, they will wait for information from the remote packet response. When the remote host is connected, it will send back a network packet. If no message is sent back, then it means the host is not available. Apart from obtaining IP address information, the ping command is used to measure packet loss, the packet sent and received, and the network responds to speed. To run the IP lookup, enter the ping command below
