All reports from hosts that contains 127. or ::1/128 in the address send the report with empty in IPADDR value to the server. For example, 192.168.127.25 will send empty IPADDR.
The problem seems to be on file IPv4.pm or IP.pm in all operating systems in all versions.
This line is the problem:
AIX/IPv4.pm: if(/^\s*inet\s+(\S+).*/){($1=~/127.+/)?next:push @ip, $1};
BSD/IPv4.pm: ($1=~/127.+/)?next:push @ip, $1
Linux/Network/IPv4.pm: ($1=~/127.+/)?next:push @ip, $1
MacOS/IPv4.pm: ($1=~/127.+/)?next:push @ip, $1
Solaris/IPv4.pm: if(/^\s*inet\s+(\S+).*/){($1=~/127.+/)?next:($ip{$1}=1)};
Solaris/Bios.pm:#Kernel version: SunOS 5.10 Generic_127112-07
If we change to:
Linux/Network/IPv4.pm: ($1=~/^127.+/)?next:push @ip, $1
the report send the IPADDR value.
The same for IPv6 in version 2.3.
Linux/Network/IP.pm: ($1=~/::1\/128/)?next:push @ip, $1;
Linux/Network/IP.pm: ($1=~/::1/)?next:push @ip, $1;
The solution is the same on the regex, including ^ before ::1.
