Hi,

finally, RHEL/CentOS systems with enabled EPEL repository can get ipv6calc via usual way.

Just note that the distributed versions are compiled having GeoIP and IP2Location support enabled by dynamic library loading, means if system has GeoIP and/or IP2Location library installed, this is detected and features are extended (if related databases are downloaded to the system).

Hope this helps, Peter
