Summary
Lancaster Lebanon Intermediate Unit 13
education research infrastructure
A school service agency with 29 BGP neighbours and 20 IPv6 prefixes cut into a descending staircase.
What it's used for
- A regional education service agency's network. 4,096 addresses in a single IPv4 prefix alongside 20 IPv6 prefixes, with 29 observed BGP neighbours.
Notable
206.82.16.0/20carries the netnameLAN-LEB-IU-13, registered to the agency.- The IPv6 announcements run
2620:1d5::/39,2620:1d5:200::/39,2620:1d5:400::/38,2620:1d5:800::/38,2620:1d5:c00::/39,2620:1d5:e00::/40,2620:1d5:f00::/41,2620:1d5:f80::/42and onward, each smaller than the last. - Three addresses were queried for reverse DNS and none returned a name.
Interesting
- That staircase is one allocation taken apart the way binary arithmetic requires. Covering a range that is not a power of two forces exactly this pattern: halve, halve again, and keep halving until the remainder is covered. Every operator who has ever announced an odd-sized range has produced the same shape, and every one of them has been asked by an upstream why they cannot just send one route.
- 29 neighbours is an extraordinary number for an organisation whose job is supporting school districts, and it says the agency is the routing hub for those districts rather than a customer of one. Public education builds its own regional carriers because commercial ones will not serve the rural half of a county at a price a district can pay.
- The IPv6 footprint dwarfs the IPv4 one, which is the correct shape for a network built after the addresses ran out and unusual for one that predates it.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
