When an FQDN node resolves to multiple addresses, the nodes for the resolved-addresses may not be correctly created.
Some addresses returned by DNS resolution may cause the node to disappear from the BIG-IP system.
-- An FQDN node resolves to multiple addresses in an address pool. -- The DNS resolution gives a subset of the addresses in the pool instead of returning all the addresses.
Set up the DNS server to always return all the addresses. In other words, DNS information needs to be stable and complete to be used a source for auto populate.
