About this network

Sixty-five thousand addresses, one route, and no abuse contact listed anywhere.

What it's used for

• A private bank's network. One IPv4 /16 announced from Switzerland, no IPv6, sixty-five thousand addresses, across two observed BGP neighbours.

Notable

• The block lists exactly one registrant, the bank's own technology department, with no abuse role at all.
• The netname is a seven-letter contraction of one half of the bank's name, from before the merger that produced the current one.
• The whole holding is a single /16, announced complete, with no more specific pieces.
• Two neighbours carry all sixty-five thousand addresses.
• Three addresses were queried for reverse DNS and none returned a name.
• No IPv6 is announced.

Interesting

• No abuse contact means a complaint has nowhere obvious to go. For a network that hosts nothing public that is a small risk, and it is still a gap in a record that exists to be contactable.
• A contraction of a predecessor bank's name has outlasted the merger in the one field nobody has to update. The holder name changed; the netname did not.
• Two banks in this number range hold a whole /16 each and announce it as one route. Both date from when a large institution could simply ask for one.
