Expired DomainsRanked by the links they kept.

Dropped .com domains that had a real website, ranked by the authority their backlink profile still carries. Every name here was checked against the registry before it was listed, so the list says available only when the registry does.

Filter by name

Minimum authoritySort byMoz data

KA: Kalenux Authority, 0–100. The domain's percentile position by inbound-link strength. KA 60 beats about three quarters of the web. Not Moz DA or Ahrefs DR — different data, different scale.
Hosts: How many distinct hostnames existed under the domain (www., blog., shop. and so on). A rough test of whether this was a real site or a parked page. Very high counts usually mean a hosting platform rather than one website.
DA & Spam: Moz Domain Authority and Spam Score, fetched for the strongest-ranked domains only. Spam is 0–100 and lower is better. Anything above 10 is pushed to the bottom of the list regardless of its other scores, because inherited spam history is what gets a rebuilt site filtered. A blank means we have not checked that domain yet, not that it is clean.
Last seen: When a live site was last captured here. This is not an expiry date: once a domain leaves the registry, the registry keeps no record of it, so the real expiration is unrecoverable. Treat this as the earliest point the domain could have lapsed.
Since: The year the Wayback Machine first captured a live site here. A domain online since 2004 is a different proposition from one since 2023, and neither KA nor DA shows you that.
Global rank: Its position among the roughly 135 million domains the link graph ranks, lowest first — this is the default ordering. It carries more detail than KA: 270 of the domains here share KA 93 while spanning ranks 515,000 to 1,728,000, so KA alone cannot separate them. Only domains with some inbound links are ranked at all.

How this list is built

Four steps, run on a schedule. The numbers below are what the pipeline actually measures, not estimates.

The whole .com zone, once a day

We hold ICANN CZDS access for .com and take the zone file each day: 5.09 GB compressed, 177,289,575 unique domains. Today's list is compared against yesterday's, which gives every name that left the registry.

Authority from the real link graph

Each dropped name is matched against the Common Crawl host graph, which ranks around 135 million domains by harmonic centrality over their actual inbound links. That is where KA comes from. A name with no entry has nothing linking to it.

Verified against the registry

A domain missing from the zone file is not necessarily free: a registered name on hold, or one with no nameservers, is simply not delegated. We measured this on a random sample — only 61.7% of zone-absent names were genuinely available. So every row is confirmed by RDAP before it is listed.

Re-checked every hour

A good expired domain is often registered within minutes of release, so a once-a-day list is wrong for most of the day. Listed names are re-checked hourly against the registry and drop off this page as soon as someone takes them.

What KA is, and what it is not

KA is Kalenux Authority: a 0–100 percentile position derived from harmonic centrality in the Common Crawl domain graph. It is built the same way the familiar authority metrics are — from the number and quality of linking domains — but it is computed from Common Crawl data, not from any vendor's index. It is not Moz DA, Ahrefs DR, or Majestic Trust Flow, and the numbers will not match theirs. Treat it as a ranking signal for comparing these domains with each other, not as a score to quote elsewhere.

Two honest limits. The link graph is republished roughly quarterly, so KA reflects the web as Common Crawl last measured it rather than this morning. And a high KA tells you a domain had links, not that they were good links: check the backlink profile yourself before buying, since expired domains can carry spam history that no centrality score will show you.
