Yeah, but it's not an exact science, any way you slice it. I just did a quick crunch of yesterday's data from our web proxy logs, and accesses of URIs based on the FQDN "b.scorecardresearch.com" (a banner ad site, I believe) had over 570 different combinations of website content categories, depending on URI. One FQDN, 570 different possible ways one might want to direct the traffic. DNS-based approaches simply may not have the granularity necessary to get the job done.
Speaking of web proxies, that should probably be the *first* thing that gets put into place, if the goal is minimize "disfavored" web traffic from traversing expensive WAN connections. - Kevin -----Original Message----- From: bind-users <bind-users-boun...@lists.isc.org> On Behalf Of Grant Taylor via bind-users Sent: Wednesday, June 27, 2018 11:04 PM Cc: bind-users@lists.isc.org Subject: Re: Domain name based multihome routing?

I can see the value for services that have FQDNs that resolve to IP addresses outside of their ASN(s) like Google / YouTube. -- Grant. . . . unix || die _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
