13 names timed out — their status is unknown, not "absent".
No common subdomains responded
None of the common subdomain names we probe resolved for polyfill-fastly.net. The domain may use only its apex record, or host subdomains under names we don’t include in the default probe list.
We probe 112 common subdomain names via DNS — a guess list, not an inventory; names that time out are reported as unknown rather than absent. For a full certificate-transparency-based inventory, see crt.sh.
