Bug: Gives warning and ends up with duplicate IPs in output... #28
Description
This is probably an edge case, but I figured still worth reporting...
I'm attaching a file combined.txt
which is a concatenation of the cymru full bogons & cidr-report bogons lists.
When you run the command iprange -v combined.txt > combined.ipset.txt
It gives the warning: iprange: WARNING: invalid range reversed start=224.0.0.0 end=0.255.255.255
.. and the end file combined.ipset.txt has loads of duplicate IPs (CIDRs) in it. If you also look at line 3073 you will see it wrote 224.0.0.0 with no CIDR. So I'm guessing the bug is something to do with the next few entries in the original file that bork the processing and it just dumps the rest of the input to output. (There was already a 0.0.0.0/8 at the beginning of the file, the one in the sample below would be the start of the 2nd concatenated file).
224.0.0.0/4
240.0.0.0/4
0.0.0.0/8
If you process them as individual files then it works just fine, ex: iprange -v cymru_full.netset cidr-report.netset > this_works.ipset
Hopefully it's an easy fix... lol
