Summary
CarMax Enterprise Services
enterprise legacy
CARMAX-AS belongs to CarMax Enterprise Services, LLC, the technology and
shared-services arm of CarMax, the largest used-car retailer in the United
States, headquartered near Richmond, Virginia.
What it's used for
- Corporate networking for CarMax: stores, offices and the company's own customer-facing systems.
- A single directly-registered
/23(199.34.126.0/23, netnameCESL-24), announced together with its two component/24s. About 512 addresses in all.
Notable
- Enterprise address space. A retailer of this size runs most of its estate behind private addressing and cloud services, so the public footprint is small.
- The low AS number is not early-internet pedigree. ARIN records both the ASN and the address block as registered in 2025, so AS7909 is a reissued number that came back into the free pool and was handed to a modern holder. Do not read a 1990s history into it.
Interesting
- This is a clean example of why a four-digit AS number tells you nothing on its own: neighbouring numbers in the same range are genuine 1997 legacy allocations, while this one is barely a year old.
