WHOIS is a public directory where you can look up "who is" responsible for a domain or IP address. For better accuracy, we use several IP geolocation databases (IP2Location LITE,ĝB-IP Lite and MaxMind GeoLite2) and choose the most appropriate result. IP-based geolocation is the process of identifying the geographical location of an internet-connected device by its IP address. The Reverse DNS Hostname is resolved by querying the DNS server for a pointer (PTR) record. Reverse DNS lookup or reverse DNS resolution (rDNS) is the querying technique of the Domain Name System (DNS) to determine the domain name associated with an IP address. Read about the benefits of our tool here: 7 Reasons Why You Should Choose Our IP Address Lookup Tool. The tool also represents the IP address in different formats: as IPv4, in decimal format and as compressed IPv6. Geolocation includes continent, country, region and city as well as the geographical coordinates (latitude and longitude). It is also able to find the geolocation of an IP address and show its location on the map. In this case, the IP address returned by the DNS lookup will be used. It supports both IPv4 and IPv6 address types.

IP Address Lookup is a free online tool that reports detailed information about an IP address, including reverse DNS hostname, organization, ASN and IP whois. To look up more formats of 144.208.68.34, visit the IP Address Converter » Useful resources Searching the database until now shows everything working normal.For the IPv4 addresses, we display IPv4-mapped IPv6. # select * from ip_country where $ipaddress<=ip_to limit 1įoreach (qw(REMOTE_ADDR HTTP_CLIENT_IP HTTP_X_FORWARDED_FOR HTTP_X_FORWARDED HTTP_X_CLUSTER_CLIENT_IPĪnd this is the output of this testing code: IPV4 : 197.36.107.146 # Now you can search the geo database with IPV4 and IPV6 stored as decimails Print "User IP address in IPV6 format: $user_ip\n" # if user remote address is IPV4 convert it to IPV6 Print "Detected User IP address: $user_ip\n" $user_ip ||= $ipaddress # just for testing on command line # detect the user ip address and convert it My $ip = new Net::IP ("::ffff:".$ipaddress) or die (Net::IP::Error()) My $ip = new Net::IP ($ipaddress) or die (Net::IP::Error())

Since I use Perl, here are some helping code for testing and clearing. The next step is to convert your IP either IPV4 or IPV6 to Decimail (39,0) and you can now search the database normal. IPv4-compatible IPv6 addresses was ::192.0.2.128Īnd this article also good on this issue:Īll you need to do is prepend the IP with ::ffff: so the IP address 192.0.2.128 will be ::ffff:192.0.2.128 as valid IPV6. Remaining 32 bits written in the customary dot-decimal notation of IPv4. One may see theseĪddresses with the first 96 bits written in the standard IPv6 format, and the Next 16 bits are one, and the remaining 32 bits are the IPv4 address. In these addresses, the first 80 bits are zero, the IPv4-mapped IPv6 addresses Hybrid dual-stack IPv6/IPv4 implementations recognize a special class of addresses, To convert IPV4 to IPV6, this wiki article is the answer: This way your application supports both IPV4 and IPV6. The trick I used here to use the IPV6 database file for both versions of IP's IPV4 and IPV6 is to convert the IPV4 address when searching the database to IPV6 then to Integer and do the search normal. The IPV4 can be embedded in IPV6 and this file contains the IPV4 embedded as IPV6 and all IPs are stored as decimal(39, 0). I am answering my own question after two days of search and testing.
