AS14148 — EXLIBRIS
AS14148 announces 19 IPv4 prefixes covering 40,704 addresses and 4 IPv6 prefixes.
About this network
The largest block belongs to the parent company, one registrant field holds a role instead of a name, and the addresses that answer do so under a third company's domain.
What it's used for
- A library software company's network. 40,704 addresses across 19 IPv4 prefixes plus four IPv6 prefixes, with nine observed BGP neighbours.
Notable
- 165.215.0.0/17, the largest block, carries the netname PROQUEST-NET, registered to PROQUEST LLC.
- Eight blocks carry EXLIBRIS-NETWORK-1 or EXLIBRIS-20-1, registered to Ex Libris (USA) Inc.
- 31.186.254.0/24 carries INAP-AMS004-exlibrisusa-31-186-254-0, with the registrant recorded as Abuse Contact.
- 64.74.237.0/24 carries INAP-CHG-EXLIBRISUSA-56957.
- Two of eighteen sampled addresses returned a name: mcfls-sra.iii.com and er25-sdc.iii.com.
Interesting
- A registrant field reading Abuse Contact records a role where a company should be. The record was built from whichever object the software found first, and nothing rejected it.
- That same netname mixes upper and lower case, which almost nothing else in the corpus does. It was assembled by a provider's system out of a site code, a customer name and the block itself.
- The reverse names belong to a domain that is neither the registrant's nor the parent's. Library software companies have merged repeatedly, and the DNS is the slowest layer to catch up.
- Four naming conventions across nineteen blocks: the parent's, the company's own, a provider's site-coded form and a provider's ticket-numbered form. Each records who handed the space over rather than who uses it.
