The subscription request containing a delivery URL not on the same network segment as the
fully qualified event subscription URL shall not be accepted. For private networks this means
that the delivery URL provided will adhere to the following IP ranges:
• 10.0.0.0 - 10.255.255.255 (10/8 prefix)
• 172.16.0.0 - 172.31.255.255 (172.16/12 prefix)
