Nice—another big shard. I’ve expanded the clustering so this chunk cleanly rolls up a bunch of new brands (Epik, BookMyName/Scaleway, RU-CENTER, Ascio/Tucows, easyDNS, eName, Bizcn, Alibaba/HiChina, Domeneshop, Donweb, RegistryGate, Pananames, Automattic/WordPress.com, Nominet, Kagoya, Hosting.kr/Megazone, PA Vietnam, IDwebhost, Domains.co.za, Neubox, etc.).

Drop this in as a replacement for your name_family helper and re-run:

def name_family(name, email_dom, url):
    n = (name or "").lower()
    u = (url or "").lower()
    ed = (email_dom or "").lower()

    # Large shard clusters

    return ""

This will also collapse lots of the Newfold/NetSol and GoDaddy “country” shards, plus the DotMedia/XZ.com set you pasted (Threadagent, XZ.com, DomainName Highway, etc.).

Want me to add any more buckets (e.g., RU brands beyond RU-CENTER/R01, or more EU hosts like LWS, Register4Less, Domeneshop variants)?
