Summary
StepBroBD, Inc.
research legacy
STEPBROBD is a small personal and research network run by Yifei Sun, a distributed-systems/HPC PhD researcher, incorporated as StepBroBD, Inc. in Portland, Oregon. RIS sees just 2 IPv4 prefixes (512 addresses), 7 IPv6 /48s, and 7 observed neighbours.
What it's used for
Self-hosted services and networking experimentation, not commercial hosting. The IPv4 footprint is two /24s (192.104.136.0/24 and 23.161.104.0/24); the IPv6 side is the larger half, with seven /48s announced individually, all of them adjacent within 2602:f590::. The one sampled PTR, isere.sd.ysun.co, sits under the operator's own personal domain and is named for the French Isère department, consistent with a machine hosted near the operator's academic base rather than in a customer-facing datacentre.
Notable
The transit mix is the giveaway that this is a hobbyist-grade network rather than an enterprise one: upstreams drawn from budget and community-friendly carriers (Vultr's The Constant Company, xTom, Virtua Systems and a personally-held ASN) instead of the tier-1s an eyeball or corporate network would buy. Seven neighbours against 512 addresses is exactly the shape of a single operator multihoming for fun and for measurement work.
Interesting
This is a recycled legacy number. AS numbers in the 10,000s were handed out in the late 1990s, but ARIN records show 10779 registered to its current holder in 2023, so the low number carries none of the history it appears to. PeeringDB self-classifies the network as Educational/Research; that is the operator's own label, and the routing is small enough that it neither confirms nor contradicts it.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
7 upstream, 1 downstream and 14 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
