AS12768 — ER-TELECOM-AS

AS12768 announces 27 IPv4 prefixes covering 149,760 addresses and 2 IPv6 prefixes.

About this network

149,760 addresses in 45 prefixes, reaching the internet through exactly one neighbour.

What it's used for

• A Russian broadband provider. 149,760 addresses across 45 IPv4 prefixes, 10 IPv6 prefixes, and one observed BGP neighbour.

Notable

• Three /18s lead the inventory: 46.146.0.0, 46.146.128.0 and 46.147.0.0.
• Netnames split between dated RU-RAID- entries (20100202, 20101013, 20120209, 20120725) and named ones: ERTH-PERM-PPPOE-1-NET and ERTH-PERM-PPPOE-2-NET.
• The IPv6 blocks run 2a02:2698::/43, then :20::/45, :28::/46, :2c::/46, :30::/44, :40::/42, :80::/41, :100::/40, :200::/39.
• Reverse names use x as the separator and carry a class marker: 46.147.16.0 answers as 46x147x16x0.dynamic.perm.ertelecom.ru, while 46.146.207.255 is 46x146x207x255.static-business.perm.ertelecom.ru.

Interesting

• One neighbour against 149,760 addresses is as lopsided as this measurement gets. Everything the subscribers reach arrives through a single adjacent network, which for a large regional operator usually means the group's own backbone sits in a different AS number and this one is purely the access layer.
• PPPOE in a netname records the technology the block was bought to serve. Address space assigned to a session-based access system gets used and reused as subscribers connect, which is why the same operator's other blocks are labelled static-business in DNS.
• That IPv6 run is one range decomposed into CIDR, not nine allocations: each prefix doubles the last as the tool walks up to fill a size that is not a power of two.
