ipv6calc is IPv6 address format change and calculation utility

Introduction

In this tutorial we learn how to install ipv6calc on CentOS 8.

What is ipv6calc

ipv6calc is a small utility which formats and calculates IPv4/IPv6 addresses in different ways. Install this package, if you want to retrieve information about a particular IPv4/IPv6/MAC address (-i ADDRESS) or make life easier in adding entries to reverse IPv6 DNS zones (e.g. -a 2001 In addition many format and type conversions are supported, see online help and/or given URL for more. Also this package contains additional programs - ipv6loganon - ipv6logconv (examples included for use with analog) - ipv6logstats (examples included for use with gnu-plot) - mod_ipv6calc Support for following databases - IP2Location ENABLED default directory for downloaded db files (requires also external library on system) - GeoIP v2 ENABLED default directory for downloaded db files (requires also external library on system) - db-ip.com v2 ENABLED (once generated database files are found on system) default directory for generated db files - External ENABLED default directory for generated db files Built WITH shared-library Available rpmbuild rebuild options –without ip2location –without mmdb (which disables GeoIP v2 and db-ip.com v2) –without external –without shared –without mod_ipv6calc
