This guide documents the classic version of the AWS Wickr administration console, released before March 13, 2025. For documentation on the new AWS Wickr administration console, see [ Administration Guide](https://docs.aws.amazon.com/wickr/latest/adminguide/what-is-wickr.html).

# Ports and domains to allow list for your Wickr network
<a name="allow-list-ports-domains"></a>

Allow list the following ports to ensure Wickr functions correctly:

**Ports**
+ TCP port 443 (for messages and attachments)
+ UDP ports 16384-16584 (for calling)

## Domains and addresses to allowlist by Region
<a name="ip-addresses"></a>

If you need to allowlist all possible calling domains and server IP addresses, see the following list of potential CIDRs by Region. Check this list periodically, as it is subject to change.

**Note**  
Registration and verification emails are sent from `no-reply@amazonaws.com` and `donotreply@wickr.email`.
