Sean,

Yes there is a way to do that. Depending on the logic you are using, /cidr/xxx.xxx.xxx.xxx/yy[/more|less] queries are probably what you are looking for. For instance, http://whois.arin.net/rest/cidr/192.149.252.0/24/more will list the networks more specific to the CIDR given. /more gives you a list of networks more specific, /less gives you a list of networks less specific, and if you do not use either it will return a network if it is exactly matching the CIDR.

The documentation for that query is here: https://www.arin.net/resources/whoisrws/whois_api.html#whoisrws under section 4.4.3.

I hope that helps.

Hi All,
                Instead of checking the start ip and end ip, likehttp://whois.ote.arin.net/rest/ip/65.127.10.160 and
http://whois.ote.arin.net/rest/ip/65.127.10.191, do you have something likehttp://whois.ote.arin.net/rest/ip /65.127.10.160/maskNo/27<http://whois.ote.arin.net/rest/ip%20/65.127.10.160/maskNo/27>? So we can check if the netBlock is swiped in one call instead checking by ip addresses for 32 times.
In this case of mine, checking only 65.127..160 and 65.127.10.191 is not good enough because both ips are not swiped, but there are 8 ips, 65.127.10.176 - 65.127.10.183 are swiped. They are between the ip 65.127..160 and 65.127.10.191. So if you have a netBlock checking, it would be great for me.

Thanks
