Summary

Japan Airlines

Japan · AI-generated

airline corporate business japan

The AS handle JAL is held by Japan Airlines Co.,Ltd.

What it's used for

  • The space carries corporate infrastructure for the airline, evidenced by the netname JAL and registrant IRT-JPNIC-JP.
  • The inventory consists of a single IPv4 prefix, 163.211.0.0/16, totaling 65536 addresses, with 0 IPv6 prefixes announced.
  • With only 1 observed neighbour, the low ratio of addresses to peers indicates an internal corporate estate rather than a transit or access network.

Notable

  • The registrant IRT-JPNIC-JP aligns with the announcer, confirming the space is directly managed by Japan Airlines.
  • The address inventory is a single contiguous /16 block, typical for a large enterprise maintaining a dedicated internal network segment.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
