AS15322 UPWARD-BROADBAND
Unclassified ARIN
Summary
Upward Broadband
isp business infrastructure
The one reverse answer is a broken record with a slash in it and the reverse zone appended.
What it's used for
- A broadband provider. Two IPv4 prefixes announced from the United States, no IPv6, and three observed BGP neighbours.
Notable
- The single answering address returns
upwardbb.161-38-34-/21.net.34.38.161.in-addr.arpa, which is not a valid hostname. - It contains a slash, a character no hostname may hold, and it ends with the reverse lookup zone for the block itself.
- That ending is the giveaway: the record was written without a trailing dot, so the DNS treated it as a relative name and appended the zone it was defined in.
- Both blocks share one netname, the company name, and one registrant, so the registry side is consistent.
- Six addresses were queried for reverse DNS and one returned a name.
Interesting
- This is the most instructive mistake in this range because it is so common and so rarely seen in the wild. A missing dot at the end of a record turns an absolute name into a relative one, and the zone origin gets glued on.
- The slash suggests the record was copied from a prefix notation rather than typed as a hostname, which means the value was pasted from a spreadsheet or a ticket into a field expecting a name.
- Nothing breaks visibly. The lookup succeeds and returns a string, so the error survives until somebody tries to use the answer.

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 2026-10-18, 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: 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.
