Arin Whois

net searches

[wilderness]

Sometime ago I inquired as to the procedure for sub-net searches. I've looked and looked both manually and with searches and was unable to find that thread in the archives.
At the time I could not get the newly designed Arin pages to respond as suggested in their help.

I stumbled :) across my old notes.

The old procedure was "net 63.160." which resulted in a limit of 255 lines.

The new procedure is "> 63.160." with no line limit.
This new method however doesn't produce identical results as comapred to the old method. As just the 63.160." block subranges.
Instead the results returned are the entire range of which that example (63.160.) block are included.
In this particular instance 63.160-175 and all subsets.

This present format is hardly useable. Not sure whether it's a flaw in the Arin search system or it was designed in intentionally. In either event it is in effective :-(

I think that they have changed a bit wilderness.

[ww2.arin.net...]

It is possible to request access to the bulk whois data but it probably is at least a few GB in size.

jmcc,
Many thanks.
Their pages are quite difficult to navigate and
comprehend :(
In addition there are conflicts in their help pages explanations.
I have a mail into them (which another was replied to previously) hopefuly that may provide some insights. I add any updates.

I tried the web interface Don,
It kept rejecting queries as if it could not handle the spaces. The whois.pl seems to work though

[ws.arin.net...]

It seems to default to checking the NET option which means that it will go through the subdelegations for NET-63-160-0-0-1 which is the Sprint NetHandle rather than the netrange. It looks like a problem in that it does not check ranges or accept a ranges modifier. (Or at least it is not that clear from their docs.)

I tried limiting the search using the! NET-63-160-1-* and it worked successfully - limiting the results to 63.160.1.0 and just listing the subnets in that range. It looks like the only way to do it would be to search on! NET-aaa-bbb-ccc-ddd or some variant.
