different answers from google's authoritative servers

Hi all, We have 3 recursive resolvers on the same subnet, and one of them is getting different answers for the same things from google's authoritative dns servers. [root@syz3ns01 ~]# RESOLVERS="ns1.google.com. ns2.google.com. ns3.google.com. ns4.google.com." [root@syz3ns01 ~]# SITES="www.google.c

Whether the responses to the query work properly in the browsers is a different issue. There's nothing inherently wrong with multiple and different responses to queries in different subnets or regions. From: "Sotiris Tsimbonis" To: "Kevin Kretz" Cc: bind-us...@isc.org Sent: Wednesday, Jun

There's also no reason to assume that the different responses have anything to do with the client network. They could, of course (with views), but that you get different responses from the same/similar IP is, again, not anything wrong. From: "Sotiris Tsimbonis" To: "Kevin Kretz" Cc: bind-u

I don't know what you mean by "the wrong logical answer". I get a different set of changing IPs when querying ns3.google.com than you, so the set you're getting likely is dependent on your IP/location. 74.125.141.99 74.125.141.106 74.125.141.103 74.125.141.105 74.125.141.147 74.125.141.1
