IP resources and IT services for networks that need to grow.
We buy, sell, lease and vet IPv4, IPv6 and ASN resources, and run the IT around them: consulting, cloud hosting and infrastructure. Registry paperwork is handled in-house.
IP Resources
Buy, lease or sell address space and autonomous systems. Every block can be audited before it is routed.
IT Services
Dedicated and cloud servers, consulting and hands-on infrastructure work from the team that runs our own network.
Know what you're buying before it's routed
A block with a bad history costs more than its price. We audit addresses and their owners, then clean up the listings that are already there.
IP security audit
Blacklists, spam routing, media and threat-intelligence checks, with a reputation score per block.
What we checkASN background check
Current and historical holders, routing history and sanctions screening for an autonomous system.
How it worksA Berlin firm that is also its own registry
TA Consulting & Services GmbH is an IT consultancy and a RIPE NCC Local Internet Registry. Because we are the registry of record, transfers and leases don't wait on a third party.
