The NetScaler supports the import of location database CSV files. Here are the supported file formats up to NetScaler version 12.0

root@NS1# nsmap
nsmap [[-h] [-d] [-dbfile <filename> || -dbfile6 <filename>] [-f <format name>] [-o <file name>]] | [-l] file
   -h prints this message
   -f specifies format of the input file
      netscaler (default)        - netscaler format
      ip-country                 - IP-Country format (ip2location.com)
      ip-country-isp             - IP-Country-ISP format (ip2location.com)
      ip-country-region-city     - IP-Country-Region-City (ip2location.com)
      ip-country-region-city-isp - IP-Country-Region-City-ISP (ip2location.com)
      geoip-country              - GeoIP country (maxmind.com)

      geoip-country6             - GeoIP Country IPv6 (maxmind.com)
      netscaler6                 - netscaler format with IPv6 addresses
   -o specifies output netscaler format file
   -l runs as daemon and communicates with the NetScaler kernel or PPE
   -d creates user space database, may be overwritten by kernel
   -dbfile name of the user space database file
   -dbfile6 name of the user space database file for ipv6 addresses
   -logfile logs data into the /var/tmp/nsmap.log instead of syslog
Test the database:
nsmap [-d] [-op] -t [ip address]   -t test the database if ip address is given - non interactive test
   -op prints database test results in old format
