About this network

The netname still joins two exchange brands together, on a merger that has since dropped one of them.

What it's used for

• An exchange operator's technology arm. Two IPv4 prefixes announced from Sweden, no IPv6, three thousand and seventy-two addresses, through four observed BGP neighbours.

Notable

• Both blocks carry the same netname and the same registration date, from the final weeks of the year two thousand, so the whole holding was signed for at once.
• That netname is a country code, two exchange brands run together with no separator, and the date. The company name in the holder field uses only the first of the two brands.
• The blocks are adjacent in the address space, the second continuing where the first ends, which is one allocation split rather than two grants.
• The registrant is the company and nothing else. There is no abuse contact, no role and no hostmaster anywhere in the record.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Exchange technology is sold as a product to other exchanges, so a company like this runs trading systems it does not own in markets it does not operate. The address space is for the software business rather than for any one venue.
• Registry records outlast branding decisions by years. The compound name in this netname was retired from the marketing long before anyone would think to edit a field nobody reads.
