How does Spamhaus SBL organize network names?
The Spamhaus Block List (SBL) records include a field assigning each record to a network identity, usually a domain but sometimes a “NETNAME” if a domain is not used in the IP-whois record. Spamhaus uses the top-level assignment of IP addresses by a Regional Internet Registry (RIR) for those SBL names. SBL notifications and Spamhaus statistics are based on those network names.
