Unclassified ARIN
Summary
Mission CISD
education k12 texas school
The AS handle MCISD-AS is held by Mission CISD.
What it's used for
- The address space carries the network infrastructure for the Mission Consolidated Independent School District, a K-12 school district in Mission, Texas.
- The AS announces 1024 IPv4 addresses within a single prefix (199.7.220.0/22) and has 2 observed neighbours, indicating a small, self-contained educational network rather than a transit or large-scale access provider.
Notable
- The RDAP registrant for the announced prefix 199.7.220.0/22 is Mission CISD, which matches the AS holder name.
- The address inventory consists of a single /22 block, typical for a local institutional network requiring a modest amount of address space for internal systems and user access.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-03, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
