free.fr / proxad / Illiad

Uses ASN 12322
To find what ASN an ISP uses: pick one IP address (not difficult: lookup their own website).

and query it at cymru:

$ dig +short free.fr a 212.27.48.10 $ whois -h whois.cymru.com 212.27.48.10 AS | IP | AS Name 12322 | 212.27.48.10 | PROXAD Free SAS

to look up the address ranges they announce in BGP, I'd use robtex: [as.robtex.com...]

if you scroll down far enough you'll get this list:
