When using cloud DNS services or centralized DNS infrastructure to enforce the correct geo-location, you can use special purpose prefixes for the country or region selection. The prefixes are hierarchically organized with continents on the top level, then regions, and then countries. Choose a prefix with the widest geographical area coverage because the prefix restricts dynamic load distribution and failover.
IMPORTANT: Use prefixes only when needed. Use of a prefix overrules the dynamic routing logic of GRM. When prefixes are used to enforce the selection of a specific geo-location, users might experience overall performance issues when traveling. An increase in network latency, dynamic failover, and load-balancing issues can occur.
Use a prefix for proxy settings to specify the preference for a PoP from a certain country or region:
- Country-specific prefix: If the host name for a proxy includes a prefix for an individual country, the closest or best PoP within the country is selected.
- Region-specific prefix: If the host name for a proxy includes a prefix for a larger region, the closest or best PoP within that region is selected.
Syntax:
- <prefix>.c<customerID>.saasprotection.com
- <prefix>.c<customerID>.wgcs.mcafee-cloud.com
For example:
- Web Gateway Cloud Service Country-specific prefix for the United Kingdom is:
uk.c12345678.saasprotection.com
- Unified Cloud Edge Country-specific prefix for the United Kingdom is:
uk.c12345678.wgcs.mcafee-cloud.com
CAUTION: Using an IP address instead of a host name for proxy settings is not supported.
If no PoP is available in the country or region specified in the proxy host name, the preconfigured fallback is to use the closest PoP regardless of the country or region. (It is unlikely that no PoP is available.)
To use the nearest PoP from the selected country or region for the endpoint, use the following predefined set of prefixes (subdomains):
