Summary

Robert College

Turkey · AI-generated

education business private

The AS handle ROBERTCOLLEGE-AS is held by Private American Robert College.

What it's used for

  • The address space carries the network infrastructure for a private educational institution, as indicated by the netname Robert_College and registrant Private American Robert College.
  • The inventory consists of 256 IPv4 addresses within a single /24 prefix (91.216.170.0/24) and 0 IPv6 prefixes. With only 1 observed neighbour, the low address-to-neighbour ratio suggests a small, self-contained site network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant Private American Robert College aligns perfectly with the AS holder and the announced netname.
  • Robert College is the oldest private high school in Istanbul, established through the merger of the American College for Girls and Robert Academy in 1971.
  • The address inventory is minimal, consisting of a single contiguous /24 block with no IPv6 allocation.

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 1,771 prefixes, as published 2026-10-15. 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.
