Hi,
I don’t think you can do much here.
If I remember correctly the JVM in the IS is set to cache DNS data indefinitely, so once an address is mapped, it will keep that IP until he server is restarted.
If, however, you are using a proxy service (for instance, SAg Mediator) you could change its definition without having to change the IS’s facing interfaces.
Hope this helps.
