AS13438 announces 10 IPv4 prefixes covering 9,216 addresses and 0 IPv6 prefixes.

About this network

One hostname answers for addresses in five different blocks.

What it's used for

• A United States hosting provider. 9,216 addresses across ten IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• sanguine5.viviotech.us is the reverse name for addresses in five separate prefixes.
• A sixth address answers as sanguine.viviotech.us, the same name without the number.
• Eight blocks are netname VIVIOTECH; one is ABSG-04-01, registered to a different company.
• One prefix's registry lookup failed, so nothing is known about its registration here.

Interesting

• The same name on the last usable address of five unrelated blocks is a gateway naming convention. Each block's router answers to the same host, because it is the same router, and the reverse zone for each was pointed at it individually.
• Naming machines after moods or humours rather than function is a hosting provider's habit from when the fleet was small enough to remember. The numbered sibling is what happens when the scheme outlives the first machine.
• Ten prefixes from ten unrelated ranges is space bought piece by piece as it became available, which is the only way to grow in IPv4 now. The single foreign netname is one of those purchases whose registration was never transferred.
