AS12735 — ASTURKNET

AS12735 announces 161 IPv4 prefixes covering 148,992 addresses and 33 IPv6 prefixes.

About this network

446 neighbours, and reverse DNS that sorts every address into a product category by domain suffix.

What it's used for

• Access and transit in Turkey. 146,688 addresses in 166 IPv4 prefixes, 164 IPv6 prefixes, and 446 observed BGP neighbours.

Notable

• The oldest allocation is TR-TURKNET-960328, dated March 1996; later ones run 990212, 20081126, 20110112 and 20110513.
• Twelve of eighteen sampled addresses answered, under five different suffixes: dsl.static.turk.net, dsl.dynamic.turk.net, srv.turk.net, static.turk.net and reverse.turk.net.
• All the names write the address backwards, as in 255.143.70.95.dsl.static.turk.net.
• The IPv6 announcements are cut into /45s, /46s, /47s and /48s out of 2a02:ff0.

Interesting

• The suffix is the product. An address under dsl.static is a fixed line, dsl.dynamic a pooled one, srv a server range, and each of those carries different expectations for mail reputation, abuse handling and filtering. Publishing the classification in DNS lets every receiving system on the Internet apply the operator's own categories without being asked to.
• 446 neighbours is one of the highest counts in this stretch of the number range. That is the profile of a network selling transit and peering aggressively at exchanges rather than one simply serving subscribers, even though it clearly does both.
• 164 IPv6 prefixes against 166 IPv4 ones is unusual and expensive. Most operators take one v6 block and announce it whole; splitting v6 as finely as v4 imports every routing-table cost of the older protocol into the newer one, on purpose.
