Unclassified ARIN
Summary
City of Columbia, MO
government telecom infrastructure
Every field agrees, and then the reverse names write the address backwards.
What it's used for
- A city government's network. One IPv4 prefix announced from the United States, no IPv6, two hundred and fifty-six addresses, through two observed BGP neighbours.
Notable
- The AS handle, the netname and the registrant are the same string: the words for a city, its name and a two-letter state code.
- The single block is registered to the city itself and is the whole announcement.
- All three queried addresses answered, on a domain that begins with the word go, then the city name and the state code run together.
- Each name is the address with its four parts in reverse order, hyphenated, so the last part leads and the first trails.
- Two observed neighbours carry the one block.
Interesting
- An address written backwards in a reverse name is the lookup zone's own ordering left in place. The zone is queried in reverse, and a generator that builds the label from that order rather than from the address produces this without anyone noticing.
- A promotional domain fronting a municipal network is a tourism and services brand doing double duty. The registry says city government; the reverse zone says visit us.
- Three fields in exact agreement on a public body is the ordinary result of one office filling in one form once, which is rarer here than it sounds.

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: 443 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.
