It seems that you have found the very same issue I have already documented:
http://hamradio.ucsd.edu/mailman/private/44net/2013-March/000848.html
https://github.com/hessu/rip44d/issues/7
Unfortunately I haven't heard back from the author or someone else and
I'm not a perl developer, so I cannot fix it myself.
Best regards,
Marc
Quoting lleachii(a)aol.com:
The populated route reads:
44.182.21.0 via 89.122.215.236 dev tunl0 onlink window 840
44.182.21.0 is a valid IP address on the ICANN Internet and does not
imply a subnet in any form.
It should contain a /24 notation as in the AMPRPortal:
44.182.21.0/24 via 89.122.215.236 dev tunl0 onlink window 840
No AMPR networks on my routing table (populated by RIP44d) contain the
proper CIDR notations.
