AS14495 ASN-14495

A stock exchange whose netnames name the parent block rather than the announcement, and whose addresses say nothing at all.

What it's used for

• A stock exchange operator's network. 10,752 addresses across 11 IPv4 prefixes, with four observed BGP neighbours and no IPv6 announced.

Notable

• Five blocks carry the netname 198-55-128-0-1, registered to Nasdaq, Inc., though the announcements themselves start at 198.55.192.0.
• Others carry NET-206-200-0-0-1, NET-204-13-72-0-1 and NET-204-153-100-0-1, all registered to the same company.
• The lookup for 206.200.255.0/24 failed, so nothing is known about that record.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• The netname writes out the parent allocation, not the block being announced, so a reader who takes the label at face value will look in the wrong place. It is accurate about ownership and misleading about location, which is a common trap in registry data.
• The trailing digit on those netnames is a sequence number, the registry's way of distinguishing several records that would otherwise carry identical labels. It survives into the public record as a piece of database housekeeping nobody meant to publish.
• Four neighbours for a network this size is about resilience rather than reach. An exchange that stops being reachable stops being an exchange.
• Not one address answered a reverse lookup. For a venue where the machines at these addresses talk only to counterparties who already know where they are, naming them publicly would add risk and nothing else.
