AS12161 — DAO

AS12161 announces 6 IPv4 prefixes covering 2,304 addresses and 1 IPv6 prefixes.

About this network

Six small blocks under five different registrants, announced from one consulting company's AS.

What it's used for

• Hosting and business connectivity. 2,304 addresses in six IPv4 prefixes, one IPv6 /44, and three observed BGP neighbours.

Notable

• Only one block is registered to the AS holder: 199.74.222.0/24, netname DAO-222.
• The others belong to four other names — MEDWEB (Nexsys Corporation), ANI (Arlington National Industries), OSCOMP (Osborn Consulting and Arlington National Industries) and TAAFFENET (Medical Data Productions).
• The IPv6 announcement is 2620:124:1000::/44, a direct assignment.

Interesting

• The reverse DNS is inconsistent in two ways at once. One address answers host-222-127, a bare label with no domain attached at all, which is not a usable name anywhere. Others alternate capitalisation between daoCon.com and daocon.com on adjacent addresses in the same /24.
• Two of those netnames point at medical work — a web platform and a data company — which is the kind of customer that outlives its provider's paperwork. Small blocks assigned in the 1990s keep being announced by whoever inherited the relationship, and the registrant field becomes a list of everyone who was ever involved.
