If the 'A' record for an FQDN node is removed or replaced on the DNS server, then the BIG-IP system does not remove the old ephemeral pool member or create the new pool member and node.
Ephemeral pool member and nodes are not removed or updated when the DNS 'A' record is removed or changed.
-- FQDN nodes. -- Pool members with a service port of ANY.
There is no workaround at this time.
Upon a DNS 'A' record being removed or changed, the ephemeral pool members and nodes based on the old value are removed or changed.
