I ran some queries earlier today on the crt.sh DB, to find all CNs,
dNSNames and iPAddresses in all unexpired certs whose issuer names
include either "WoSign" or "StartCom". Then I cross-referenced that
with the latest PSL data to discover the unique base domains:
Someone contacted me off-list (thanks!) to point out that my lists were
incomplete. I'd missed a load of base domains delegated below the new
gTLDs. (I hadn't spotted that my local copy of
https://data.iana.org/TLD/tlds-alpha-by-domain.txt was rather out of date).
Updated count and gists...
WoSign:
Unique Base Domains: 127,355
StartCom:
Unique Base Domains: 259,712

WoSign:
Unique CNs/dNSNames: 395,222
Unique Base Domains: 118,785
Unique IP Addresses: 154
StartCom:
Unique CNs/dNSNames: 706,020
Unique Base Domains: 249,841
Unique IP Addresses: 0

While you are at it:
1. How many WoSign/StartCom certificates did you find with domains not
on that IANA list?
2. How many WoSign/StartCom certificates did you find for other uses
than https://www.example.tld:
2.1 Certificates for "odd" subdomains such as "extranet.example.com"
2.2 Certificates for e-mail
2.3 Code signing certificates
2.4 Others?
Enjoy
