About this network

MFX-AS is operated by Syntis SARL.

What it's used for

• The address space carries business and internal infrastructure traffic, evidenced by netnames MODELFX, ERTUS3, and RESOLUTIO, and reverse DNS entries such as neogiciel1.syntis.net and preprod.mygeorges.fr.
• The AS announces 3072 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small-scale access or business network rather than a transit provider.
• Traffic from this AS consists of corporate office workers, web/API endpoints, and branch backhaul for Syntis and its associated entities.

Notable

• Registrants for most prefixes are SYNTIS SARL, while the 5.83.234.0/24 prefix is registered to D2E SAS, suggesting a leased or acquired block.
• The address inventory is finely subdivided into small /23 and /24 blocks, consistent with an internal corporate estate or a small regional ISP serving specific business clients.
