AS16426 CITYOFCOLUMBUSOHIO
Unclassified ARIN
Summary
City of Columbus
government infrastructure business
The handle runs five words together including the state; the netname keeps two of them and hyphenates in the wrong place.
What it's used for
- A municipal government's network. One IPv4 prefix announced from the United States, no IPv6, eight thousand one hundred and ninety-two addresses, through two observed BGP neighbours.
Notable
- The AS handle is the words for city, of, the city name and the state, run together with no separators at all, leaving one long string a reader has to parse by eye.
- The netname keeps only the first three words, drops the state, and puts its single hyphen after the word for of rather than before it, so the split falls in the middle of a phrase instead of between two.
- The registrant is the same short name the netname uses.
- All three queried addresses answered, each with its own address written out in four hyphenated parts, the word for a fixed assignment, and the government's own domain.
- One answer sits on the first address of a subnet, which normally identifies the network rather than a host. It answers anyway, so the reverse zone is generated across the range rather than per machine.
Interesting
- A municipality that publishes reverse names on its own domain tells anyone who looks which addresses belong to the city. That helps a service desk and helps anyone mapping the city from outside just as much.
- Two spellings of one owner in two registry fields is the ordinary outcome of two people filling in two forms far apart.

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 1,778 prefixes, as published 2026-10-20. 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.
