<div dir="ltr">Hi list<br><br>I'm making use of the riswhois service and would like to cache queries locally. However, I am not sure whether I can do it the way I want to. My idea is to store the ASN an the corresponding route of each query I execute. Before performing another query I would then check whether I already stored the ASN of a route which contains the IP for which I want to find the AS.<br>
Can I do that? Or is then the following case possible: I store an AS an its route -- say ASx, <a href="http://123.0.0.0/8">123.0.0.0/8</a> -- whose IP range includes another one -- say ASy, <a href="http://123.100.0.0/16">123.100.0.0/16</a>. When I store ASx first and then query an IP of ASy, I will assign ASx to this IP instead of ASy. Is such a case possible? Or is there even another problem with my caching approach?<br>
<br>Thanks for your time!<br><br>Best,<br>Laurent<br></div>
