AS12321 — ES-IBERCOMTELECOM-BACKBONE

AS12321 announces 11 IPv4 prefixes covering 18,176 addresses and 0 IPv6 prefixes.

About this network

Xtra Telecom is a Spanish operator selling connectivity to businesses, and its address space still answers to an older name.

What it's used for

• Business internet access. Every sampled address resolves under ibercom.com with a static. prefix and the octets reversed, as in static.254.53.7.212.ibercom.com — the naming a provider uses for fixed assignments rather than a dynamic pool.

Notable

• 18,176 addresses across eleven prefixes, one observed BGP neighbour, no IPv6 announced.
• Nine of the eleven blocks share the single netname IBERCOMNET, while 212.166.80.0/20 is registered separately as ES-MUNDITELECOM-20000809, dated the 9th of August 2000.
• The registry contact on every one of them is the MasMovil abuse team.

Interesting

• Three company names are visible at once, and none of them is the same as the next. The AS handle says Ibercom, the holder is Xtra Telecom, one netname says Munditelecom, and the contact says MasMovil. Spanish telecoms consolidated hard, with MasMovil assembling itself from a series of smaller operators before merging upward again, and each acquisition left its name in a different field.
• Reverse DNS is the layer customers notice, and it still says ibercom.com. Changing it means renumbering nothing, but it means touching every record for a cosmetic gain, so the brand a business customer sees in a traceroute can be two owners out of date.
