recursion
2 TopicsCan BIG-IP DNS recursion only my domain?
Hi We are using F5 DNS as DNS server and have many CNAME record. We want to query those CNAME record and then get IP as a result too. (Which solved by Enable "recursion yes; in named configuration) But we found problem that our F5 DNS perform recursion on EVERY domain client asking. (eg. f5.com, nginx.com., etc.) We want F5 DNS to answer query on only domain we handle (many domain in zonerunner and gslb) How can we do that? Is it possible to do that? because "recursion yes;" is config on named configuration. I think it's global configuration. and "allow-recursion {}" is only check for client IP address (it's not check on domain we handle) Thank you11Views0likes1CommentZoneRunner and custom root hints
Hi, I am fighting with customizing root hints used by ZoneRunner (on VE 13.0.0HF2), I did everything according to this article Configuring a root.hint zone for use with the BIG-IP DNS system but I failed. If I paste content of the file get from link in article root hints then dig . NS @ is working. If I modify IP in any entry in db.external.named.root. (doing stop start for named and zrd after mod) like changing . 3600000 NS A.ROOT-SERVERS.NET. A.ROOT-SERVERS.NET. 3600000 A 198.41.0.4 A.ROOT-SERVERS.NET. 3600000 AAAA 2001:503:ba3e::2:30 to . 3600000 NS A.ROOT-SERVERS.NET. A.ROOT-SERVERS.NET. 3600000 A 198.41.0.5 A.ROOT-SERVERS.NET. 3600000 AAAA 2001:503:ba3e::2:30 I am getting exactly same response to my query - no change in IP for A.ROOT-SERVERS.NET If I delete all entries and leave something like that: . 3600000 NS mydns.test.com. mydns.test.com. 3600000 A 192.168.1.254 ;A.ROOT-SERVERS.NET. 3600000 AAAA 2001:503:ba3e::2:30 then response to the same query is server failure What I am doing wrong then, or maybe it's a bug? My goal is to send all queries from LDNS to my DNS server that then should be responsible to provide answer to A query. In situation like described BIG-IP is handling recursion, sending requests to all NS in a chain (starting from root) - not what I need. Piotr373Views0likes0Comments
