AS12980 AT&T Global Network Services Nederland B.V.

Three companies in one record: one names the AS, one names the handle, and one holds every block.

What it's used for

• A European hosting network belonging to a corporate infrastructure services business. 13,312 addresses across four IPv4 prefixes, four observed BGP neighbours, and no IPv6 announced.

Notable

• The AS is registered to a telecommunications company's Dutch entity.
• The AS handle is Kyndryl EMEA Hosting Autonomous System.
• Every block's netname is KYN-GTS- plus its address range, registered to a third company name.
• Three of four blocks sit in 129.35, legacy class B space.
• Twelve addresses were sampled and none returned a name.

Interesting

• Another AS in this same range carries the identical registered company name while its blocks list a different corporation's network centre as contact. Put together, the two records trace one business changing hands twice: the addresses moved to a spun-off infrastructure company, the AS registration stayed with the telecom that acquired it earlier, and the handle was updated to the newest owner. No single field is wrong; no two of them agree.
• KYN-GTS-129-35 builds the netname from the owner's abbreviation, a service name, and the block itself. Generating netnames mechanically from address ranges is what happens when hundreds of blocks change hands at once and nobody is going to name them individually.
• 129.35 is old class B space from before the current registry system. Corporate hosting operations sit on address space that predates the businesses running them by decades, because the space is the durable asset and the company names are not.
