Summary

  • Reverse DNS for addresses inside 212.236.10.0/24 — an /24 announced by Datamatix's AS210973 — resolves into the video-broadcast.at namespace, and the abuse contact for the range sits in that domain rather than at Datamatix.
  • Multiple attribution sources label the /24's organisation "Rapid Solution Development", a separate Vienna entity that holds its own AS43855 under a different RIPE organisation and originates zero routes.
  • The route objects for the 212.236.x space are maintained by AS8245-MNT, the maintainer of Video-Broadcast GmbH, and the covering aggregates are announced by AS8245.
  • Datamatix's own business — wireless data links for vehicles, on-premises mine fleet management, LoRaWAN devices — has no hosting or cloud product line, and IPinfo counts only two hosted domains across the whole ASN.
  • The evidence permits per-layer sentences, not a unified verdict: registry ownership is clear, service-layer operation points elsewhere, and no public source proves the commercial arrangement between the parties.

The starting point is uncontested. DATAMATIX Datensysteme GmbH is a real Vienna company: registered in the Austrian commercial register under FN 240683x with share capital of EUR 36,000, managing director Michael Kastelic, and a procurator since 23 September 2021 https://www.evi.gv.at/f/240683x. Its imprint lists Märzstraße 1, 1150 Wien, VAT number ATU 574 395 33 and membership of the WK Wien's IT and consulting division https://datamatix.at/impressum.html. The company describes itself as developing customised solutions since 2003 https://datamatix.at/unternehmen.html — hardware and software for wireless data transmission to vehicles and objects, plus RF prototypes and measurement systems https://datamatix.at/.

Its autonomous system AS210973 was allocated on 30 July 2021 https://bgp.he.net/AS210973 and announces four IPv4 /24s — 149.62.35.0/24, 194.0.132.0/24, 212.236.9.0/24 and 212.236.10.0/24 — plus one IPv6 prefix, per the RIPE object mirror https://ipgeolocation.io/browse/asn/AS210973 and the bgp.tools profile https://bgp.tools/as/210973. IPinfo counts 1,024 IPv4 addresses across those netblocks and, notably, only two hosted domains for the entire ASN https://ipinfo.io/AS210973. For a company whose products are on-premises by design — Secall-CAN mine fleet management runs on licensed-frequency data radio with all software components on-site, deliberately without cloud dependency https://datamatix.at/produkte.html, using SATEL-TR4+ serial radios according to its supplier's reference page https://www.satel.com/references/datamatix/ — that small hosted footprint is consistent with its own product description in business directories https://www.wlw.at/de/firma/datamatix-datensysteme-gmbh-1312310.

The anomaly sits inside one of those four blocks. Look up addresses in 212.236.10.0/24 and three identity layers disagree with each other and with Datamatix. The ASN layer says AS210973, DATAMATIX Datensysteme GmbH. The company layer says "Rapid Solution Development". The reverse-DNS and abuse layer says video-broadcast.at. For 212.236.10.1, IPinfo records the hostname rsd-tik.rom.video-broadcast.at, the company field "Rapid Solution Development" and an abuse contact in the video-broadcast.at domain — while the same record's ASN field names AS210973 and datamatix.at https://ipinfo.io/212.236.10.1. A second address in the block, 212.236.10.234, resolves to 212.236.010.234.static.video-broadcast.at with the same split labels https://ipinfo.io/212.236.10.234. BigDataCloud's independent lookup corroborates the organisation label "Rapid Solution Development" for the range while still associating the BGP prefix with AS210973 https://www.bigdatacloud.com/ip-lookup/212.236.10.255.

"Rapid Solution Development" is not just a label; it is a registry entity of its own. The RIPE mirror data for AS43855 shows as-name ASN-RSD, remarks "Rapid Solution Development", held under organisation ORG-RSD1-RIPE — Werner Berghammer / RSD - Rapid Solution Development e.U., Neubaugasse 36, 1070 Wien https://ipgeolocation.io/browse/asn/AS43855. That AS43855 originates zero IPv4 and zero IPv6 routes, and its registered import/export policy names AS24953, AS33833 and AS43957 — not AS210973, AS8245 or AS8218. So the name on the /24 matches an entity that does not announce it, while the AS that does announce it belongs to a company whose products never touch hosting. A low-reliability scraped mirror additionally records the /24's registrant handle as RSD-SUB1 "Rapid Solution Development" https://rg443hh.x10.mx/hh/212.236.10.0/24; because that source is an unofficial mirror of uncertain provenance, it is corroborative only and not load-bearing here.

The routing layer fills in the mechanism. The route object for 212.236.10.0/24 reads: origin AS210973, mnt-by AS8245-MNT, created 2021-08-16 — the maintainer of Video-Broadcast GmbH, and the covering 212.236.0.0/16, /18 and /19 aggregates are announced by AS8245 https://bgp.he.net/net/212.236.10.0/24. Datamatix's aut-num policy names only AS8245 and AS24953 as its counterparts, while bgp.tools lists AS8218 (Zayo Europe) as a third upstream and shows AS210973 as a member of AS-SETs including as8218:as-at-customers and as8245:as-video-broadcast-at https://bgp.tools/as/210973. CIDR Report's adjacency shows only two upstreams, AS24953 and AS8245 https://www.cidr-report.org/cgi-bin/as-report?as=AS210973&v=4&view=6447, and zero downstreams https://www.cidr-report.org/cgi-bin/as-report?as=AS210973&view=2.0.

Prior BTW reporting had already established that AS210973's routes ride AS8245's aggregates and that the direct role of AS8218 was unresolved https://btw.media/en/datamatix-as210973-entangled-upstreams. What this investigation adds is the service layer beneath that routing question: the addresses inside the /24 do not merely transit through Video-Broadcast's infrastructure — their hostnames, abuse handling and attribution all live in the Video-Broadcast and RSD sphere. One requested source, bgp.tools' page for AS43855, could not be retrieved during this research run https://bgp.tools/as/43855, so bgp.tools-specific claims about AS43855 rest on the RIPE mirror data instead; this is disclosed rather than papered over.

The honest reading is a claim ladder, not a verdict. Held: Datamatix's LIR owns the registration and the ASN. Routed: AS210973 originates the /24, but the route objects are maintained by AS8245-MNT. Named: the range's registrant and organisation labels say Rapid Solution Development. Operated: the reverse DNS and abuse contact live in video-broadcast.at. Each rung has its own evidence. What no public source shows is the commercial contract — whether Datamatix is hosting for RSD or Video-Broadcast, lending its ASN as a registry vehicle, or sharing a corporate relationship that the record does not name.

The signals consistently point away from Datamatix operating anything inside the block it originates; they do not say who does, in what capacity, or on what terms.
