AS13183 — ISP-AS

AS13183 announces 2 IPv4 prefixes covering 4,096 addresses and 0 IPv6 prefixes.

About this network

The AS handle is ISP-AS, which here stands for the bank's initials and nothing to do with providers.

What it's used for

• The corporate network of an Italian bank. 4,096 addresses across two IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.

Notable

• The AS handle is ISP-AS; the holder is Intesa Sanpaolo S.p.A..
• Both prefixes are /21s, 62.221.168.0/21 and 62.221.176.0/21, sharing the netname IT-INTESASANPAOLO-20020422.
• The first registry contact is Admin TLC.
• First observed in the routing archive in May 2003. Six addresses were sampled and none returned a name.

Interesting

• Three letters that mean one thing everywhere else in this field mean something else here. Anything classifying networks by handle would read this as a service provider and be wrong, which is exactly the failure mode that makes handles a poor identifier on their own.
• Two /21s from one registration, announced separately rather than as the /20 they would form together. The split is internal structure made externally visible, and it doubles this network's footprint in the global table for no outside benefit.
• One neighbour for a bank is a single path out, which is less redundancy than most enterprises of this size arrange.
