+# If you do not define this value, then then InspIRCd will attempt to #
+# determine your DNS server from your operating system. On POSIX #
+# platforms, InspIRCd will read /etc/resolv.conf, and populate this #
+# value with the first DNS server address found. On Windows platforms #
+# InspIRCd will check the registry, and use the DNS server of the #
+# first active network interface, if one exists. #
+# If a DNS server cannot be determined from these checks, the default #
+# value '127.0.0.1' is used instead. The timeout value is in seconds. #
