About this network

SYSTAILOR- is operated by Systailor SAS.

What it's used for

• The address space carries corporate infrastructure, evidenced by the reverse DNS record PUBCUSTA.cust.systailor.fr and the netname FR-DELNET-20171207.
• The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, with 48 observed neighbours; this ratio of a small address block against a high neighbour count indicates a transit or peering-heavy role rather than a large access network.
• As a French IT services provider, the traffic consists of business endpoints, web/API services, and internal corporate backhaul for its client base.

Notable

• The RDAP registrant SYSTAILOR SAS matches the AS holder, confirming consistent ownership of the announced space.
• The inventory consists of a single contiguous IPv4 block (185.236.0.0/22) and one IPv6 prefix (2a0d:9306::/31), representing a compact, internally managed corporate estate.
