Summary

Specialized Bicycle Components

unknown · AI-generated

business corporate internal

The AS handle is -Reserved AS- and the holder is Specialized Bicycle Components.

What it's used for

  • The space carries internal corporate systems, evidenced by the netname SPECIALZ-1 and reverse DNS entries pointing to system.specialized.com.
  • The inventory consists of 256 IPv4 addresses within a single prefix (216.139.27.0/24) and 0 IPv6 prefixes. With only 1 observed neighbour, this indicates a small, isolated internal network rather than a transit or access provider.

Notable

  • The registrant Specialized Bicycle Components aligns with the reverse DNS evidence, confirming the space is owned and operated by the bicycle manufacturer.
  • The address inventory is a single /24 block, representing a standard-sized internal corporate estate with no external customer base.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
