IP Range for Entrust Revocation CRL/OCSP

Article Number: 46455


What is the IP range for Entrust revocation CRL/OCSP


The Entrust IP addresses used revocation checks are dynamic and globally load balanced, because of this Entrust cannot provide a set of Static IP addresses.

Other Options:

01. White list the FQDN's listed below:


02. Proxy the CRL requests to a server in DMZ.

Request to crl.entrust.net would be directed to a proxy server which has internet access. Proxy server downloads the CRL.
Implementation details are dependent on the hardware/software available to execute this setup.

03. Host the CRL internally.

Manually download the CRL and host it on the internal server.
CRL would have to be re-downloaded periodically to keep an up to date view.
