About this network

418,560 addresses and 139 announcements, reached through exactly two neighbours.

What it's used for

• A Turkish digital television platform that also provides broadband internet. 418,560 addresses across 139 IPv4 prefixes, one IPv6 prefix, and two observed BGP neighbours.

Notable

• Most sampled blocks carry the identical netname TR-DSMART-20080804.
• Two others are TR-DSMART-20000427 and TR-DSMART-20110427.
• All are registered to a network services contact alongside the parent company's full legal name.
• The registry lookup for 94.120.192.0/18 failed, so nothing here describes that block's record.
• Eighteen addresses were sampled and none returned a name.

Interesting

• Two neighbours carrying 418,560 addresses is the most lopsided ratio in this range. Everything reaching nearly half a million subscribers arrives through two upstream relationships, which concentrates an entire consumer broadband base behind a pair of dependencies.
• One netname repeated across most blocks means a single 2008 allocation that grew by acquiring adjacent space under the same record. Six /18s sharing one registration date is a very large amount of address space obtained at once, in the last years when that was still possible.
• Two of the dates are the same day of the same month eleven years apart, which is coincidence worth noting only because it is the kind of pattern that looks meaningful and is not.
• A television company holding a consumer ISP's worth of address space is the usual direction of convergence: the platform that already reaches homes adds internet, rather than an ISP adding television. The netnames name the broadcast entity, not the internet service.
