Summary
The School District of Pittsburgh
education k12 network
The AS handle SDP-ASN is held by The School District of Pittsburgh.
What it's used for
- The address space is registered under the netname
NETBLK-PGH-BOEwith the registrant listed as "The School District of Pittsburgh; Network Operations Center," indicating internal network operations for the district. - The AS announces a single IPv4 prefix, 198.206.16.0/20, comprising 4096 addresses, and has one observed neighbour, a ratio consistent with a small, self-contained institutional network rather than a transit or access provider.
Notable
- The RDAP registrant matches the AS holder, confirming the space is directly owned and managed by the school district.
- The inventory consists of a single contiguous /20 block with no IPv6 prefixes announced, reflecting a compact and straightforward address allocation for an educational institution.

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 1,784 prefixes, as published 2026-10-19. 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.
