CENTERTECH is the AS handle for The Center for Rural Development, Inc.

What it's used for

  • The space carries a single IPv4 prefix 23.152.208.0/24 and one IPv6 prefix 2620:78:6000::/48, with netname CENTERTECH-V4-1 registered to the holder.
  • With 256 IPv4 addresses announced against 1 observed neighbour, the ratio indicates a small, self-contained network rather than a transit or large access provider.

  • The address inventory consists of one /24 block and one /48, representing a minimal footprint consistent with a small organizational presence.

Reputation

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
