Summary
Johnson & Johnson
enterprise business infrastructure
Sixty-eight IPv6 announcements against nine IPv4 ones, from a company with only five thousand addresses.
What it's used for
- A pharmaceutical and consumer products company's network. 5,120 addresses across nine IPv4 prefixes, 68 IPv6 prefixes, and ten observed BGP neighbours.
Notable
- The IPv6 announcements outnumber the IPv4 ones by more than seven to one.
- Under
2602:28cthe sizes run /35, /43, /45, /48, /47 and /46, falling and then rising again. - Between
2602:280::/32and2602:285::/32several intervening blocks are never announced. - Six blocks share netname
JNJand two more areNETBLK-JNJ-CNET. - Every readable block is registered to the company itself rather than to a carrier.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- A corporate network with more IPv6 routes than most regional providers, and a modest IPv4 footprint behind them, is what happens when an enterprise deploys the newer protocol properly and never needed many of the older addresses. The routing table sees a large network; the address count says a small one.
- The gaps between announced IPv6 blocks are space the company holds and does not route, which is the luxury the protocol allows.
- Holding every block in its own name, with no carrier registrant anywhere, is unusual at this size and makes the network portable between the ten upstreams carrying it.

Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
10 upstream, 0 downstream and 14 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
