[arin-tech-discuss] zero-padded IP addresses in "startAddress" and "endAddress" values

[Dani Roisman]

Greetings,

One of our developers just pointed out to me that the values for "startAddress" and "endAddress" values are now zero padded.  Is it possible this was a result of the Mar 24th code push (http://lists.arin.net/pipermail/arin-tech-discuss/2012-March/000187.html)?  If so - was this expected, or a bug?

Here's an example from query "curl -4 https://www.arin.net/rest/net/NET-75-126-0-0-1?apikey=<snip>" (note, the API key must be authorized to the network owner if you're trying to reproduce this, try your key and your netblock)

Note that this *differs* from public whois output, for example that same netblock:

Using " curl -4 http://whois.arin.net/rest/net/NET-75-126-0-0-1"
