About this network

A Portuguese operator announcing a /16, with every block still named after a company it used to be.

What it's used for

• A Portuguese telecommunications provider. 75,008 addresses across four IPv4 prefixes, one IPv6 prefix, and ten observed BGP neighbours.

Notable

• The inventory is 213.63.0.0/16, 213.141.0.0/19, 185.113.156.0/22 and 194.60.91.0/24.
• Two blocks carry PT-JAZZTEL- netnames dated 20000329 and 20150817, fifteen years apart.
• 194.60.91.0/24 is named NET-194-60-91-0-24, a label generated from the block itself.
• The registry lookup for 213.141.0.0/19 failed, so nothing here describes that block's record.
• Twelve addresses were sampled and none returned a name.

Interesting

• Both dated netnames name a different company, and one of them was created in 2015, long after this operator took the space over. Whoever registered the newer block copied the naming pattern from the older ones rather than using the current name, so a defunct brand propagated forward into a record that had no reason to carry it.
• NET-194-60-91-0-24 is what a netname looks like when nobody chose one. The registry generates a label from the address range so the field is not empty, and the result identifies the block without saying anything about it. Every such name in the data marks a block that was created administratively rather than requested by a person.
• A /16 is 65,536 of this network's 75,008 addresses, and it dates to March 2000. Portuguese operators of that era received large blocks before allocation policy tightened, and the resulting shape is one enormous prefix with a few small modern ones attached.
