About this network

The netnames are the address blocks written out as words, and the company's own name is spelled three different ways across them.

What it's used for

• A payments software company's network. 31,232 addresses across 37 IPv4 prefixes, with six observed BGP neighbours and no IPv6 announced.

Notable

• Most blocks carry netnames that are just their parent range with dashes: NET-139-131-0-0, NET-138-229-0-0, NET-65-198-80-0-1, NET-65-222-196-0-1.
• The registrant is recorded as ACI Worldwide, Inc. on some blocks, ACI Worldwide on another and ACI WORLDWIDE on a third.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• Thirty-seven announcements are carried by six neighbours, most of them /22s and /23s cut out of 139.131.

Interesting

• A netname that restates the block is a registry default rather than a choice. It carries no information the record does not already hold, which is what happens when space is registered in bulk and nobody is asked to name it.
• Three spellings of one company across four records is the ordinary cost of filing paperwork over decades. Anything trying to group networks by organisation name has to normalise case and punctuation before it can see that these are the same company.
• A payments network that publishes no reverse names and no IPv6 gives an outsider nothing to read. The traffic is bank-to-processor over arranged links, not public browsing, so there is nothing to gain from being discoverable.
• Cutting one range into dozens of small announcements suggests processing sites turned up individually, each with its own upstream arrangement.
