XTOM-TOKYO is operated by xTom GmbH.

What it's used for

  • The address space consists exclusively of IPv6 prefixes, including 2001:df4:dd80::/48, 2a06:4fc0::/29, and 2a06:57c0::/29.
  • With 3 announced IPv6 prefixes and 1 observed neighbour, the network functions as a small-scale business or internal corporate estate rather than a transit provider.
  • xTom GmbH is a German IT services company based in Düsseldorf that provides network infrastructure and connectivity solutions.

Notable

  • The registry holder is listed as XTOM-PARK xTom GmbH, which aligns with the operator identity.
  • The AS handle XTOM-TOKYO references a Japanese subsidiary, xTom Japan Corporation, indicating international operations.
  • The inventory contains no IPv4 prefixes, reflecting a modern IPv6-only deployment strategy.

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: 442 networks and 1,773 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.
