AS15347 15347

One block in each of several national carriers' space, with each carrier's incident response team as contact.

What it's used for

• An outsourced customer service company operating sites in several countries. Ten IPv4 prefixes announced, no IPv6, across ten observed BGP neighbours.

Notable

• Six of the ten blocks are registered not to the company but to national carriers, under contact fields naming incident response teams with two letter country codes.
• Those netnames name the carriers rather than the company: one is a national telephone operator's initials, one a consumer brand, one a private limited company written with its corporate form in brackets.
• The company's own blocks use four unrelated formats, including one of two letters, one built from a transit provider's abbreviation and the address, and one naming a public pool.
• The three answering addresses are named with the full address written forwards under a carrier's domain, not the company's.
• Eighteen addresses were queried for reverse DNS and three returned a name.

Interesting

• This is what a distributed contact centre business looks like in the routing table: a small block in each country, obtained from whichever carrier serves that site, announced under one AS number.
• The incident response team contacts are the useful part. Each names the team that can actually reach the site, which is better than a corporate address that would route to the wrong continent.
• Nothing here identifies the company from the outside except the AS number itself.
