Summary
Bloomington Public School District No. 87
education k12 legacy
The network of a public school district in Bloomington, Illinois.
What it's used for
- School district connectivity. 1,536 addresses in two prefixes with one observed BGP neighbour.
Notable
- The larger block,
207.68.192.0/22, is registered to the district under the netnameILLINICLOUD— the shared computing consortium that Illinois school districts built to pool infrastructure none of them could fund alone. - The other block is registered to Verizon Business under the netname
FRONTIER-COMMUNICATIONS, and its reverse DNS answers underfrontiernet.net. - Those reverse names carry an opaque 32-character hexadecimal label between the address and the domain:
173-86-246-128.c39472bab5bc79e34b0b5dfd99d35697.ip.frontiernet.net, with a different string on every address. - First seen in the routing data in April 2014.
Interesting
- A school district running its own AS is a decision about who to depend on. Two prefixes and one upstream is not a resilience play; it is a district that wanted its address space to survive changing providers, which for a public body on a procurement cycle is the more practical risk.
- The netname and the registrant on the second block disagree because the network changed hands and the record did not follow. Frontier bought a large piece of Verizon's wireline business, and both names survive in the same entry, one in the registrant field and one in the label.

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.
