AS14962 — NCR-252
AS14962 announces 45 IPv4 prefixes covering 637,440 addresses and 0 IPv6 prefixes.
About this network
Seven hundred thousand legacy addresses, two generations of netname, and not one IPv6 prefix.
What it's used for
- A corporate network. 702,720 addresses across 46 IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.
Notable
- The largest blocks are 135.126.0.0/15 and 153.86.0.0/15, followed by four full sixteen-bit blocks: 132.242.0.0/16, 149.25.0.0/16, 153.77.0.0/16 and 153.85.0.0/16.
- Netnames fall into two families. NCRWIN6, NCRWIN17, NETBLK-NCRWIN-B and NCRWIN-C label most of the space; NCRB1 and NCRB2 label the rest.
- NCRWIN17 alone covers five separate blocks, including everything announced out of 153.84 and 153.85.
- Every block registers to NCR Voyix Corporation.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Six full sixteen-bit blocks and two larger ones is the address footprint of a company that was numbering computers before anyone had to justify the request. Nothing that size is issued now, and nothing here has been given back.
- The two netname families are two eras of the same filing habit. NCRB1 and NCRB2 name the organisation and count; the NCRWIN names add a system or site word and then count. Whoever changed the convention left the earlier records alone, which is why both are still authoritative.
- Announcing 702,720 addresses with no IPv6 at all, and with three neighbours, describes an internal estate. There is no shortage to solve when the space you were given decades ago is larger than anything you will connect to it.
