# Mimecast - Email Security Cloud Gateway - Data Centers & URLs ## Considerations - When a user enters their email address into Mimecast's Administration Console or an API client, a global resource determines the user's parent account location. This resource provides a 302 redirect to the correct location, ensuring uninterrupted service. These endpoints are available at all Mimecast data centers. - Outbound HTTPS traffic from your network may be observed to an IP address outside your Mimecast region. To avoid disruption, allow outbound HTTPS connections to these locations. No email is transmitted using this method. - Your region may be somewhere other than where you are physically located. It is where your data is located. For example, a company with European offices may host its data in North America. - You must ensure that all connections are allowed access to the ports for the networks listed and mapped to the correct destination on your network. - To prevent disruption to your service, it's important to ensure that: - You allow connections to the appropriate ports from your region's entire Mimecast IP Ranges. - They are mapped through to the correct destination on your network. ## Global Application Resources ### Global Application URL

### Protocol Connection Ports The following list shows the most common connection types and the general ports used for each protocol. Also included are the standard connection ports for Mimecast Applications:
ProtocolDefault PortUsage
Simple Mail Transfer Protocol (SMTP)25Send Connectors, SMTP Journaling, user application SMTP Services.
Post Office Protocol (POP3)110POP Journaling, user application POP Services.
Post Office Protocol Secure (POP3S)995
Lightweight Directory Access Protocol (LDAP)389Directory Synchronization
Lightweight Directory Access Protocol Secure (LDAPS)636
HyperText Transfer Protocol (HTTP)80Downloading Strip and Link attachments, Mimecast Synchronization Engine (MSE) with Office 365 hybrid environments. Mimecast for Outlook also authenticates using this port.
HyperText Transfer Protocol (HTTPS)443Access to the Administration Console, Mimecast Personal Portal, Mimecast Mobile, Mimecast for Outlook, and Mimecast Synchronization Engine, Mimecast E2E, Customer Managed Migration.
### Mimecast Website To ensure that your users can always log in to the Mimecast website, it is recommended to permit traffic to the Mimecast website IP ranges:

## Regional IP Addresses, Network Ranges, and Application URLs ### Europe (Excluding Germany) #### IP Addresses and Network Ranges
**Note:**When entering IP ranges, it is essential to note that Microsoft 365 limits the CIDR you can use on the Connection Filter (e.g., 205.139.110.0/23 or 185.58.84.0/22). We recommend breaking up the ranges so they end in/24 as a workaround.

### Australia #### IP Addresses and Network Ranges
**Note:**When entering IP ranges, it is essential to note that Microsoft 365 limits the CIDR you can use on the Connection Filter (e.g., 205.139.110.0/23 or 185.58.84.0/22). We recommend breaking up the ranges so they end in/24 as a workaround.

## Mimecast URL Scanning Activity

When monitoring IP addresses associated with clicked links in your environment, you may observe activity that does not originate from Mimecast-owned IP addresses or IP addresses listed on this page. As part of the Mimecast threat detection stack, the URL scanning layer can utilize various 3rd party vendors whose IP ranges are subject to change and are not tracked or disclosed by Mimecast. Furthermore, Mimecast employs anonymization techniques to prevent threat actors from recognizing and evading our scanners. To protect Mimecast customers, the associated IP addresses will not be disclosed.
