Multiple IP Address Checker
Fetch the IP address for multiple domain names using our free Multiple IP Address Checker tool. What is an IP Address? IP address stands for Internet Protocol Address. An IP address is a numerical address assigned to every device being used on a computer network using the Internet protocol. The World Wide Web uses IP addresses to track every device and computer on the Internet so that they can communicate and exchange information to keep the network functioning. Nearly every device has an IP address on an Internet connected network, but a local network will sometimes share a single IP address for Internet access. For example, a business network might be assigned a single IP address for the Internet, and all devices on the private network share that IP address for Internet access. However, each individual device is usually assigned a local IP address of it's own for the local network. Websites have IP addresses too. When you type in an URL in your browser, your request is sent off to your ISP where the domain name is converted into an IP address by checking the DNS records for the domain. The IP address is then used to make an HTTP request to fetch the website.
Multiple Reverse IP Lookup
Perform multiple reverse IP address lookups with our Multiple Reverse IP Lookup tool. This tool accepts a list of multiple IP addresses, and performs a reverse lookup to obtain the hostname that the IP address maps to. What is a Reverse IP Address? Reverse IP address is simply a term for discovering the hostname that an IP address translates to. Since all web sites have an IP address in order to be connected to the World Wide Web, that IP address is found from the domain name using DNS nameserver records. However, sometimes you want to discover the hostname of the server on a network and all you have is the IP address. A Reverse IP lookup is really a Reverse DNS lookup, since it uses nameserver records to determine the domain name for an IP address. rDNS is the opposite of normal DNS lookups which are performed with most domain name requests, since it maps the domain name out from the IP address. Reverse DNS lookups can be useful if you have a list of IP addresses to check, or need to learn more about where a request is coming from when all you have is the IP address. For example, extracting IP addresses from Web server logs and determining the origin of the requests using only the IP address.
Ping a domain or IP address! This simple, straightforward tool with ping an IP address or domain name. The Ping tool will send a simple HTTP request and, if available, will return the IP address of a domain name as specified. The ping tool is just a simple way to see if a website or server is live using the domain name or IP address. What is a Ping? In computer networking, ping is a networking tool to check the status of a connected device. Traditional ping tools on a network would use the ICMP Internet Control Message Protocol to send a test request packet to a device, then await the ICMP response and signal to the network administrator that a device was online. The term Ping is also used more loosely to indicate a "poke" or test across a network, even if it's isn't strictly using the ICMP ping network tool. The Ping Domain & IP Address tool does not use ICMP network pings, but instead a standard HTTP request to determine if a domain or IP address is responding. If you enter a domain name to ping, our ping tool will also try to determine the associated IP address for the domain name and provide it in the response for you. The ping tool can be used to quickly test the response of a site, and see if a domain or IP address is working or taking significantly longer than it should.
Reverse IP Lookup
Our Reverse IP Lookup tool will check any IP address for the corresponding domain name. Enter any IP address, and our IP lookup will try to determine the original hostname of the IP address based on rDNS records. What is a Reverse IP Lookup? Every website or computer connected to the Internet has a unique numerical address called the IP address. The IP address is required for requests & responses to communicate with any device online. Of course, typing in a bunch of numbers to visit our favorite websites would be extremely difficult! It's much easier to use a domain name so we have something easy to remember - but the network communications uses the IP address for reliable communication. Normally when you enter a domain name in your browser, it will then route the request to your ISP where they will perform a domain name lookup by checking DNS records for the domain. The IP address for the web server is provided in the DNS records, and you can then fetch responses directly from the server by IP address. If you have a list of IP addresses from server logs, a list of IP addresses for your own websites, or just need to test a few devices, our reverse IP lookup tool will perform a reverse lookup and try to fetch the domain names for each of your IP addresses.
