# AdvertiseByoipCidr


Advertises an IPv4 address range that is provisioned for use with your AWS resources through bring your own IP addresses (BYOIP). It can take a few minutes before traffic to the specified addresses starts routing to AWS because of propagation delays. 

To stop advertising the BYOIP address range, use [ WithdrawByoipCidr](https://docs.aws.amazon.com/global-accelerator/latest/api/WithdrawByoipCidr.html).

For more information, see [Bring your own IP addresses (BYOIP)](https://docs.aws.amazon.com/global-accelerator/latest/dg/using-byoip.html) in the * AWS Global Accelerator Developer Guide*.
