varnish-purge-proxy will cache the IP lookup for 60 seconds, you can change this as follows:

AWS

Specify tags to limit instances that receive the purge request, multiple tags can be used. You must specify at least one tag.

GCE

Specify an instance name prefix to limit instances that receive the purge request with the --nameprefix argument.
