About this network

Reverse names ending in .sft, a top-level domain that does not exist, and a PTR for every broadcast address.

What it's used for

• Corporate networking for a contract vehicle manufacturer. 5,120 addresses in four IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

• Three blocks share the netname MAGNA-STEYR-FAHRZEUGTECHNIK-AT-NET-1; 213.150.252.0/22 is MAGNA-EUROPE-NET01, registered to MSI-IT Hostmasters.
• The registry contact on the first three is an SFT Role Object.
• Reverse names take two forms: 193.187.202.0 answers as rev-193-187-202-0.sft, while 193.187.203.255 answers as broadcast203.magnasteyr.com.
• Nine of twelve sampled addresses returned a name.

Interesting

• .sft is not a top-level domain. Nothing on the public internet can resolve a name ending there, which means these reverse records were generated by a system that appends an internal suffix — SFT, the same abbreviation the registry contact uses — and nobody stripped it on the way out. The records are published to the world in a namespace that only exists inside the company.
• Every address ending in .255 answers as broadcastNNN.magnasteyr.com. The zone generator was told which addresses are broadcast addresses and labelled them, using the real company domain rather than the internal suffix. Two different tools wrote this zone.
• Two netnames, two hostmaster identities and two naming conventions in one four-prefix inventory is a company that has merged its networks on paper faster than in DNS.
