AS3786 — LGDACOM-KR - LG DACOM Corporation

AS3786 announces 2,643 IPv4 prefixes covering 8,056,832 addresses and 10 IPv6 prefixes.

About this network

LGDACOM is one of the core autonomous systems of LG Uplus, a major South Korean telecom operator. The AS still carries the DACOM name from the data communications carrier that merged into LG Uplus, and its network is widely known by the Boranet brand.

What it's used for

• Broadband and fixed-line internet access for South Korean homes and businesses.
• Domestic and international transit, peering, and enterprise connectivity for LG Uplus customers.

Notable

• One of the larger eyeball networks in this ASN range, announcing roughly 8 million IPv4 addresses.
• LG Uplus operates several ASNs alongside this one, so AS3786 is a piece of a larger network rather than the whole company.
• Multi-terabit traffic levels and hundreds of peering sessions make it a standard next-hop for anyone delivering content into Korea.

Interesting

• The "DACOM" name predates the LG Uplus brand, and the handle is a good example of a registry handle outliving the company that first used it.
