AS9842 LDCC-AS LOTTE INNOVATE Co.,Ltd

AS9842 (LDCC-AS) is held by LOTTE INNOVATE Co., Ltd., the IT services and system-integration arm of South Korea's Lotte Group. The company was long known as Lotte Data Communication (hence the LDCC handle) and provides system integration, system management and data-centre services to Lotte's retail, hospitality, manufacturing and financial affiliates.

What it's used for

This is a corporate IT and IDC network rather than an ISP. RIS sees 58 IPv4 prefixes carrying roughly 82,944 addresses, no IPv6, and only six BGP neighbours. Those two numbers together are the whole story: 83,000 addresses is a substantial estate, but six neighbours means the network is not selling transit and has no meaningful customer cone. A wholesale carrier holding this much space would peer with hundreds of ASes.

The address space is large and contiguous, drawn from three main ranges (223.253.0.0, 124.243.0.0 and 210.93.128.0), announced both as aggregates (/18 and /19) and as heavily deaggregated /19s and /20s covering the same ground. Announcing a /18 alongside its component /19s and /20s is a traffic-engineering pattern used to steer inbound traffic across multiple upstreams, and it is typical of an enterprise data-centre operator balancing across a small set of Korean carriers.

Notable

• The network serves the Lotte Group's own affiliates and IT-outsourcing customers, so the space carries corporate and hosted enterprise workloads rather than eyeballs.
• The LDCC handle preserves the old Lotte Data Communication name, which is a good reminder that the registry handle lags the corporate identity.
