IPv6

Measured 2026-11-13 02:32 UTC · aaaa.bot
B

Works over IPv6, with one gap: its nameservers lack IPv6.

rbx.com has 4 IPv6 addresses and answers on every one we tested (4 more not tested).

  • ✓ rbx.com answers (4 of 4 addresses)
  • ✓ Mail: 1 of 1 servers have IPv6
  • ✗ Nameservers: none have IPv6
Details: published addresses and what answered

Loads over IPv6 with a valid certificate: HTTP 200.

What changed (latest 8 of 23)
  1. IPv6 first measured: published, and answering on Nov 4, 2026rbx.com has 8 IPv6 addresses. Grade B. Measured by aaaa.bot, 2026-11-04 12:52 UTC. No earlier IPv6 record is held, so this is not a "gained" date.
  2. Certificates moved to Sectigo between Jun 30, 2026 and Jul 1, 2026Amazon issued the most certificates until 2026-06-30; Sectigo from 2026-07-01.
  3. DNS moved to roblox.co.uk + roblox.com + roblox.net + roblox.us between May 17, 2026 and Jun 16, 2026dns1.p07.nsone.net, dns2.p07.nsone.net, dns3.p07.nsone.net, dns4.p07.nsone.net, ns01.rbxinfra.net, ns02.rbxinfra.net, ns03.rbxinfra.net, ns04.rbxinfra.net → nspx1.roblox.com, nspx2.roblox.net, nspx3.roblox.us, nspx4.roblox.co.uk.

  6. Renewed +2 years between Jun 19, 2024 and Jul 2, 2024Expiry moved from 2024-07-25 to 2026-07-25, at MarkMonitor, Inc.
  7. Renewed +2 years between Jun 22, 2022 and Jun 29, 2022Expiry moved from 2022-07-24 to 2024-07-25, at MarkMonitor, Inc.
  8. Unusual issuer: Google Trust Services on May 13, 202111 certificates from Google Trust Services (2021-05-13 to 2022-11-29), an issuer this name rarely uses. Worth checking who requested them; not proof of anything.

Solid bar: the stretch we observed that name. Dot: a single sighting. Dotted line: no record between sightings of the same name. Nothing is drawn between different names.

Registrar and renewals: 291 WHOIS/RDAP snapshots, 2010-10-22 to 2026-05-17 (ledger built 2026-09-27). Every renewal

DNS provider, registry zone files: 120 .com zone-file snapshots held, 2013-10-18 to 2026-11-15.

DNS provider, WHOIS snapshots: 260 WHOIS/RDAP snapshots that listed nameservers, 2007-05-16 to 2026-06-29 (who.is archive). Both sources feed one row per provider (hover a bar to see which); a change is placed between the nearest observations on either side, and where the two sources disagree, both are listed under What changed.

Certificates: 5,655 logged certificates (precertificate and final counted once), read 2026-11-14, reading incomplete. A bar is the issuer that issued the most certificates in those months; Sectigo renews about every 1 days (median over 49 issuance days). Public CT logging began in 2013; older certificates appear only where someone logged them later.
