8 Best Free Online IPv6 Lookup Websites

Here is a list of the best free online IPv6 lookup websites. IPv6 is the Internet Protocol version 6. It is the most recent version of Internet Protocol (IP) and was developed as a successor to IPv4. IPv4 is still in use and it uses 32-bit addresses that provide a maximum of around 4.3 billion unique addresses theoretically. The newer IPv6 uses 128-bit addresses approximately 340 undecillion addresses (3.4 × 10^38) in total.

IPv6 lookup is the same as IPv4 lookup. An IPv6 lookup is querying a DNS server to get information about a specific IPv6 address. This information generally includes domain name, AS number, registration date, hostname, ISP, geolocation, etc. This post covers 8 websites where you can perform IPv6 lookups. Some of these websites also combine whois into the lookup information along with geodata. You can go through the post to check these websites in detail.

Frequently Asked Questions

IPv6 (Internet Protocol version 6) is an updated version of IP addressing that uses 128-bit addresses, allowing for significantly more unique identifiers compared to the previous IPv4 system. IPv6 addresses are represented in hexadecimal notation and serve as the foundation for identifying and locating devices on the internet.

IPv6 lookup refers to the process of querying databases or using tools to retrieve information about an IPv6 address, such as its ownership, geographical location, and potential reputation. This helps in network diagnostics and security assessments.

Yes, individuals can look up IPv6 addresses using online tools or command line utilities like ping6, traceroute6, and whois. These methods provide information about reachability, network path, and ownership.

You can assess your IPv6 IP reputation by using online reputation checkers or security platforms that analyze its history and behavior, helping determine if it's associated with spam, malicious activity, or other issues.

You can verify IPv6 connectivity by checking your device's network settings to ensure it has an IPv6 address, and then using online IPv6 testing tools or commands like "ping6" to confirm successful communication with IPv6-enabled websites or servers.

Yes, IPv6 includes a range of public IP addresses that can be used for direct communication on the internet. It allows devices to have globally reachable addresses without the need for NAT (Network Address Translation).

To check IPv6 status in Command Prompt, use the command "netsh interface ipv6 show address" to display configured IPv6 addresses on your network interfaces, and "ping -6 google.com" to verify IPv6 connectivity by sending a ping request to Google's IPv6 address.

If someone knows your IPv6 address, they can use it to potentially gather information about your general geographical location and identify the internet service provider you're using. However, knowing just the IPv6 address itself doesn't provide access to your personal data or directly compromise your device's security.
