GENERAL
-------
ipv6calc's internal databases

* IPv4 assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for selecting proper registry in ipv6calcweb.cgi and IPv4 anonymization)
* IPv6 assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for selecting proper registry in ipv6calcweb.cgi and IPv6 anonymization)
* ASN assignment databases from IANA, ARIN, RIPENCC, APNIC, LACNIC, AFRINIC (for IPv4/IPv6 anonymization)

can be overruled by using updated ones converted into Berkeley DB format.

	ipv6calc-create-registry-list-ipv4.pl
	ipv6calc-create-registry-list-ipv6.pl
