AS15612 — SERVECENTRIC Dublin, Ireland

AS15612 announces 4 IPv4 prefixes covering 23,552 addresses and 0 IPv6 prefixes.

About this network

All four blocks carry one netname and one allocation date, under a four-letter code that is not the company's.

What it's used for

• A hosting and colocation provider. Four IPv4 prefixes announced from Ireland, no IPv6, twenty-three thousand addresses, across seven observed BGP neighbours.

Notable

• The four blocks share a single netname down to the allocation date, so all four are pieces of one grant made on one day.
• The four-letter code inside that netname matches neither the holder's name nor its trading name.
• The AS handle continues past the company name into a city and a country.
• The four announcements come out of one range but leave two stretches of it unannounced, so the routing covers part of the grant and not the rest.
• Twelve addresses were queried for reverse DNS and none returned a name.
• No IPv6 is announced at all.

Interesting

• A code that belongs to nobody in the current record is a former company name almost every time. The grant outlived whoever asked for it.
• A hosting provider with no IPv6 is increasingly conspicuous. Customers who need it have to be told no, and that is a sales conversation rather than a technical one.
• Twenty-three thousand addresses and seven neighbours is a modest, self-contained shape for a colocation business, with the space mattering more than the connectivity.
