Make sure your registration/quarantine networks allow CRL
validation, or at least, don't redirect requests back to the captive
portal.

Is there a list of such animals by domain name?

I attached text files with the URLs for OCSP and CRL endpoints for all
of the certificates in Mozilla's root certificate bundle.

You can generate the OCSP list yourself with:
curl "https://www.mozilla.org/projects/security/certs/included/"; |
grep -E "<ocsp>.+</ocsp>" | grep -v "<\!--" | sed -E
's/.*<ocsp>(.+)<\/ocsp>.*/\1/' | sort | uniq

And you can generate the CRL list with:
curl "https://www.mozilla.org/projects/security/certs/included/"; |
grep -E "<crl url=\"[^\"]" | sed -E 's/.*<crl url=\"(.+)\".*/\1/' |
sort | uniq
