A screenshot would help Alexey troubleshooting, yes.

Does it reproduce on the demo installation?

Yes, the demo shows the capacity. I even reset my user interface and it didn't fix it.

Attached is a screenshot.

We're having this issue with an upgrade as well. I think the previous version was 19.14.

I tested the database using clean code on my local Ubuntu 12.04 machine and it shows the capacity without issue. The production Debian Squeeze machine however, has the issue reported above. We're think the issue lies in ip4_mask_size($mask) in functions.php and 64-bit vs. 32-bit machines.

A bit of sample code to illustrate the problem:

<?php
echo 0xffffffff;
echo "\n";
echo (0xffffffff >> 24);
echo "\n";
echo PHP_INT_MAX;
echo "\n";
?>

Running this on the affected 32-bit Debian box results in:
4294967295
-1
2147483647

On my 64-bit Ubuntu box the results are:

4294967295
255
9223372036854775807

Something like this might be the ticket:

function ip4_mask_size ($mask)
{
        return bcdiv(0xffffffff , bcpow('2', $mask)) + 1;
        //return (0xffffffff >> $mask) + 1;
}

All credit goes to my workmate - hopefully this helps out a bit.

This fix breaks my IPv4 view. I did a git clone and and I can't pull up the IPv4 view at all, it shows 1 network without any background or page layout.
