AS11012 DDC-AS

DDC-AS belongs to The Digital Design Company of San Antonio, Texas — a long-running local infrastructure and managed-services shop that trades today under the ddc.net domain as Durable Data Corporation, selling data centre and cloud infrastructure, security and business-continuity services.

What it's used for

Serving DDC's own hosted and managed customers, on a footprint that has barely changed in decades. RIS observes two announced IPv4 prefixes totalling 768 addresses, no IPv6, and a single BGP neighbour — a single-homed edge, not a network that resells transit.

The two prefixes tell different stories. 204.27.147.0/24 is registered in ARIN as DDC-NET, a direct allocation dating to 1994, held by Tristero, Inc. at the same San Antonio street address with a ddc.net technical contact — a related corporate entity, not an unrelated third party. The other, 204.71.88.0/23, sits inside a CenturyLink legacy Savvis block, so it is upstream-assigned space announced by the customer. That mix — one's own historic allocation plus a slice of the provider's — is the classic shape of a small regional operator that has been in the same building since the mid-1990s.

Notable

Do not confuse this with the identically named embedded-electronics firm in Arlington Heights, Illinois; the two share a name and nothing else. Identity here is settled by ARIN's postal address and the ddc.net contacts, not by the company name.
