About this network

Six blocks share a netname that says marketplace, and the addresses belong to four other companies.

What it's used for

• An address brokerage's network. Nine IPv4 prefixes announced from Germany, no IPv6, two thousand five hundred and sixty addresses, across four observed BGP neighbours.

Notable

• Six of the nine blocks carry one netname naming the operator and a marketplace, and every one of them lists an abuse role as its only registrant, with no company named.
• The other three belong to three different companies: a consulting firm, a technology company whose netname begins with a country code that is not the one the blocks are announced from, and a rural wireless operator.
• One of those netnames is the word for a network followed by a date from the early nineteen-nineties, the oldest allocation date anywhere in this stretch of numbers.
• Another is the word for a network followed by the block's own octets and a trailing digit.
• The nine blocks come from nine unrelated ranges, eight of them a /24 and one a /23.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Address space is traded, and this is what the trade looks like in the routing table: blocks from four owners in different places, announced together by a company whose product is the transfer rather than the connectivity.
• A netname that says marketplace is unusually honest. Most brokered space keeps whatever name it had before it changed hands.
