About this network

A bank holding a full /19, with a netname that names its website rather than the bank.

What it's used for

• The network of a Turkish commercial bank. 8,192 addresses in one IPv4 prefix, three observed BGP neighbours, and no IPv6 announced.

Notable

• The single prefix is 213.148.64.0/19, netname TR-TEBWEB-20000303.
• The AS handle is TEBBANKA Istanbul Turkey, giving a city and a country.
• Three observed BGP neighbours.
• Three addresses were sampled and none returned a name.

Interesting

• WEB in the netname says what the block was requested for. A /19 registered as web space in early 2000 is a bank building its first public internet presence, and the label has outlived whatever that presence was by a quarter of a century.
• Eight thousand addresses is a great deal for a bank's public services and very little for its branches. Whichever it was for, the block has been announced whole ever since without being split, which is the opposite of what the fragmented entries elsewhere in this range did with far less space.
• Three neighbours for a financial institution is the arrangement the AS number exists to provide: more than one path out, so a single provider failure is survivable, and no more complexity than that.
