About this network
FR-OC3NETWORK belongs to OC3 Network SAS, a French cloud and hosting provider based near Montpellier (Pérols, Hérault). It sells IaaS, PaaS and managed cloud services, and runs its own datacentre network.
What it's used for
- Server and cloud hosting. The address space is ~8,200 IPv4 out of 212.44.224.0/19, plus a 194.0.176.0/24, announced through two upstreams. No IPv6.
- rDNS is unambiguous server naming: srv-IP-DASHED.apo.mtp.oc3n.net — mtp for Montpellier — along with mail exchangers (mx2.oc3n.net) and named customer hosts.
Notable
- The customer hosts that do resolve are French businesses and hosting resellers running on OC3's space (for example syloe.net, a Montpellier managed-cloud firm, occupying several contiguous /24s). That is a normal hosting-provider inventory: one operator's block, subdivided among service customers, all under first-party rDNS conventions.
- No subscriber-access naming appears anywhere — no dsl-, ppp- or dynamic pools. This is a datacentre network, not an ISP.
Interesting
- The srv- prefix on almost every delegated name makes this AS unusually easy to read. Where many hosting providers leave customer space undelegated, OC3 auto-generates a name for each address, so the shape of the network is visible from rDNS alone.
