About this network

A netname dated 05052015, with the year last: a fourth date format in one range.

What it's used for

• A pan-European backbone carrier. 531,456 addresses across 138 IPv4 prefixes, 97 IPv6 prefixes, and 2,327 observed BGP neighbours.

Notable

• DE-EUN-SUBALLOC-05052015 puts the year at the end, unlike every other dated netname here.
• Other netnames are DE-EUNETWORKS-20000609 through DE-EUNETWORKS-20041006, plus NET-SAGE on a /16.
• The AS handle is LAMBDANET-AS European Backbone of AS13237, containing its own AS number.
• Three sampled addresses answered 0-64-124-83.dsl.3u.net, a third party's domain.

Interesting

• Eight digits that read year-first everywhere else in this range read day-first here, and only context distinguishes them. Whether 05052015 is the fifth of May is unknowable from the string, which is what happens when a free-text field accumulates local conventions.
• 2,327 neighbours is the highest count seen across this range by a wide margin, and it is the whole description of the business: this network's product is the number of other networks it reaches.
• A handle that names its own AS number is circular, and it is also the clearest label in the record, because the trading name has changed at least twice and the number never has.
• The reverse names come from a DSL provider's domain, so parts of this backbone carry access traffic under someone else's branding.
