IP addresses 0.0.0.0 – 126.255.255.255 originate from United States. In the meantime, IP addresses 127.0.0.0 – 255.255.255.255 originate from Japan. Right here we’re making a database “IP2Location” with desk “IPCountry” that consists of two IP handle vary information.
Step 1: Create and hook up with ‘IP2Location’ database
mysql> CREATE DATABASE IP2Location
mysql> CONNECT IP2Location
Step 2: Create ‘IPCountry’ desk
mysql> CREATE TABLE IPCountry
–> (
–> ipFROM DOUBLE NOT NULL,
–> ipTO DOUBLE NOT NULL,
–> countrySHORT VARCHAR(2) NOT NULL,
–> countryLONG VARCHAR(100) NOT NULL,
–> PRIMARY KEY(ipFROM, ipTO)
–> );
Step 3. Import the ‘ipcountry.csv’ database into desk ‘IPCountry’
mysql> INSERT INTO IPCountry VALUES (0, 2130706431,’US’,’UNITED STATES’);
mysql> INSERT INTO IPCountry VALUES (2130706432, 4294967295,’JP’,’JAPAN’);
