AS12912 announces 188 IPv4 prefixes covering 1,092,864 addresses and 17 IPv6 prefixes.

About this network

A national mobile carrier whose address blocks are still named after the brand it replaced.

What it's used for

• The mobile network of a Polish operator. 1,092,608 addresses across 209 IPv4 prefixes, 19 IPv6 prefixes, and 316 observed BGP neighbours.

Notable

• Eight of the twelve sampled blocks carry the bare netname ERANET, with no date and no country prefix.
• Two more are PL-ERANET-20090401 and PL-ERANET-20100203.
• Two are PL-ENERGIS-20010801 and PL-ENERGIS-20020903, registered to a different operator's IP team alongside the current holder.
• The AS handle is TM.
• Fifteen of eighteen sampled addresses returned names, in three forms: 178.180.128.0.nat.umts.dynamic.t-mobile.pl, 37.31.64.0.mobile.internet.t-mobile.pl and 188.147.191.254.mobile.static.t-mobile.pl.

Interesting

• ERANET names a mobile brand that no longer exists. The company rebranded, the reverse names were all updated to the new name, and the netnames were left exactly as they were. Reverse DNS is customer-facing so it gets fixed; netnames are seen by almost nobody, so they become the most reliable record of what a company used to be called.
• The reverse names sort subscribers into three classes and say so plainly: carrier NAT over the mobile network, ordinary mobile internet, and static addressing. Anyone receiving traffic can tell which kind of connection it came from before doing anything else, which is exactly what abuse and fraud systems use these names for.
• The ENERGIS blocks are a fixed-line operator absorbed into a mobile one, and both companies' contacts are still listed on them.
