One address per row
Five rows of that build, as the file has them:

total counts the registered domains that resolve to the address, each through its own A or AAAA record or its www name's, following a CNAME. domains lists them in one cell: all of them, or the 1,000 most popular where there are more.
The most popular first
14,912 addresses carried more than 1,000 domains, and popularity decides which 1,000 each of their rows lists, so a row opens on its most popular domains rather than the first names in alphabetical order. 198.185.159.144, one of the four addresses Squarespace gives its customers for a domain's A record, carried 8,437,829, and its row opens on datareportal.com, distill.pub, wedrawthelinesca.org, stability.ai, techsafety.org and pixar.com.
The address pages on internetdata.io show an address's count and its most popular domains, as on 198.185.159.144.
IPv4 and IPv6
| IPv4 | IPv6 | |
|---|---|---|
| Addresses | 10,932,719 | 20,789,671 |
| With one domain | 6,952,002 (63.6%) | 20,295,941 (97.6%) |
| With 2 to 10 | 3,213,833 | 372,210 |
| With more than 1,000 | 12,902 | 2,010 |
| Domain and address pairs | 461,132,339 | 122,428,656 |
On IPv4, the 12,902 addresses with more than 1,000 domains carried 79.4% of the pairs, and 43 addresses carried half of all IPv4 pairs. Read total before the names: a handful of domains on an address can be one owner's, and a million are one platform's customers.
What it covers
It counts the domains in Domain List: every registered domain in the generic TLDs and in .ee, .fr, .nu, .se and .sk, and the domains in use under the other country codes, .de and .uk among them. Loopback and other reserved addresses are left out.
By range and by network
Two more files joined IP Hosted Domains on November 12, grouping the same domains: Range Hosted Domains has each announced IP range with the AS announcing it, and ASN Hosted Domains has each AS. A row counts the domains that resolve into its range or AS and lists up to 1,000 of them, the most popular first. The November 12 build had 352,177 ranges, 19,344 of them IPv6, and 47,138 ASes, AS16509 the largest with 65,833,366 domains.
Getting access
IP Hosted Domains ships as CSV, rebuilt weekly, and its docs have each file's schema. Sign up to evaluate it from its sample. A license is per database and never metered: see licensing, or talk to us about what you need. In BigQuery, the address file is a listing of its own.
