AS13693 — NTS-ONLINE

AS13693 announces 94 IPv4 prefixes covering 161,536 addresses and 1 IPv6 prefixes.

About this network

One IPv6 allocation chopped into fifteen announcements at prefix lengths almost nobody uses, alongside 164 IPv4 prefixes.

What it's used for

• A fibre provider. 161,536 addresses across 164 IPv4 prefixes, fifteen IPv6 prefixes, and nine observed BGP neighbours.

Notable

• The IPv6 pieces run at /38, /39 and /40, sizes that sit between the round numbers registries hand out.
• Netnames carry two brands: the current one in VEXUS-CGNT-NET-1, and an older abbreviation in NTSC, NTSC-CGNT-NET-1, NTS-ONLINE-2BLK and NTS-ONLINE-5BLK-1.
• The AS handle still names the older brand, and a middle segment in several netnames names a transit provider.
• One block sits in 145.224, space administered by a different regional registry.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Cutting IPv6 at odd prefix lengths is what happens when an operator treats a huge allocation like a scarce one and subdivides it by hand. There is no shortage to justify it, and each extra piece is another entry every router carries.
• Three generations of brand sit in the netnames at once, and the AS handle is stuck on the oldest, which is the usual order: routing identifiers change last.
• 164 IPv4 prefixes for one provider is a fragmentation record for this part of the table, and the addresses were clearly assembled from many small purchases rather than one allocation.
