How To Disable Reverse DNS Queries For Incoming IPs in OAG.
Last updated on SEPTEMBER 20, 2016
Applies to:Oracle API Gateway - Version 11.1.2 and later
Information in this document applies to any platform.
It was noticed in network logs that OAG performs reverse DNS queries for incoming server IPs.
For example, when a sever with IP 220.127.116.11 calls OAG, the Gateway makes a reverse DNS query:
queries: info: client 10.101.13.68#50491: query: 250.85.205.212.in-addr.arpa IN PTR
This causes network latency.
Is it possible to disable the reverse DNS queries being performed?
