<div class="">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,
<a href="http://whois.arin.net/rest/cidr/192.149.252.0/24/more" class="">http://whois.arin.net/rest/cidr/192.149.252.0/24/more</a> 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.</div>
<div class=""><br class="">
</div>
<div class="">The documentation for that query is here: <a href="https://www.arin.net/resources/whoisrws/whois_api.html#whoisrws" class="">
https://www.arin.net/resources/whoisrws/whois_api.html#whoisrws</a> under section 4.4.3.</div>

<div class="">I hope that helps.</div>

Hi All,<o:p class=""></o:p></div>
<div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
Instead of checking the start ip and end ip, like<i class=""><a href="http://whois.ote.arin.net/rest/ip/65.127.10.160" style="color: purple; text-decoration: underline;" class="">http://whois.ote.arin.net/rest/ip/65.127.10.160</a><span class="Apple-converted-space"> </span></i>and<o:p class=""></o:p></div>
<div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
<i class=""><a href="http://whois.ote.arin.net/rest/ip/65.127.10.191" style="color: purple; text-decoration: underline;" class="">http://whois.ote.arin.net/rest/ip/65.127.10.191</a></i>, do you have something like<i class=""><a href="http://whois.ote.arin.net/rest/ip%20/65.127.10.160/maskNo/27" style="color: purple; text-decoration: underline;" class="">http://whois.ote.arin.net/rest/ip
/65.127.10.160/maskNo/27</a>?</i><span class="Apple-converted-space"> </span>So we can check if the netBlock is swiped in one call instead checking by ip addresses for 32 times. <o:p class=""></o:p></div>
<div style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">
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,<span class="Apple-converted-space"> </span><span style="color: rgb(31, 73, 125);" class="">65.127.10.176 - 65.127.10.183
are swiped. They are between the ip<span class="Apple-converted-space"> </span></span>65.127..160 and 65.127.10.191. So if you have a netBlock checking, it would be great for me.<o:p class=""></o:p></div>
