>how can i have to 2 ips resolve from one domain name ? here are some examples: dig aol.com mx dig hotmail.com mx dig microsoft.com mx When a hostname has identical fields for network class and Rtype, the group of records is call an RRset. BIND treats the set as indivisible, and will answer queries with the entire set. The RRset-order option defines the physical order of the set members in an answer. The default order is cyclic. You can see these params either globally for alll zones in the named.conf options sections, or per-zone in the zone statements. This is a load-distribution technique, not load balancing. see http://www.isc.org/products/BIND/docs/config/ Note that the BIND resolver will, in the case of NS records, also play a role in that it will lock onto the NS that has the lowest RTT, round trip time, while continuing to query all the NSīs in the NS RRSet to check their RTTīs.
