Network type: hosting

AS16406 announces 6 IPv4 prefixes covering 18,432 addresses and 0 IPv6 prefixes.

About this network

Eight different addresses answered reverse DNS with the same name: the company's bare domain, no host part.

What it's used for

• A hosting provider's network. Six IPv4 prefixes announced from the United States, no IPv6, eighteen thousand four hundred and thirty-two addresses, through nine observed BGP neighbours.

Notable

• Ten of eighteen queried addresses answered, and eight of those returned the company's domain by itself, with nothing in front of it. Different addresses in different blocks all resolve to the same string.
• The two exceptions are on a second company's domain: one names a network engineering group, the other a mail relay with a state code and a numeral.
• Every netname is the company name with its vowels removed, then a numeral. The numbering skips a value, and the lowest number covers three separate blocks.
• Two netnames insert a two-letter state code between the name and the numeral, and their numerals restart the sequence rather than continuing it.
• The AS handle puts the letters for an autonomous system in front of the company name, which is the reverse of the usual order.

Interesting

• A reverse name with no host part is a wildcard that answers every address in a zone with the apex. It satisfies software that insists on a name and tells an investigator only which company to write to.
• The second domain in those answers is where the real machines live. The company brand faces customers and the other domain faces the engineers, and the reverse zone shows both at once.
