Unclassified ARIN
Summary
Core Transit LLC
transit legacy
The network of Core Transit LLC, an IP transit and routing provider based in Lancaster, Pennsylvania, operating under the handle CORE-TRANSIT.
What it's used for
- Providing BGP transit and IP routing to ISPs, hosting providers, and enterprises, with many peering relationships.
Notable
- A transit network that carries other networks' traffic, not a residential "eyeball" ISP.
Interesting
- Core Transit was founded in 2022, so this low AS number is a recent reassignment and carries no early-internet pedigree.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
