AS6515 — DACSIX-EAST

AS6515 announces 3 IPv4 prefixes covering 1,024 addresses and 6 IPv6 prefixes.

About this network

AS6515 belongs to DACS-IX, a Maryland-based operator that runs internet-exchange fabrics in the Washington–Baltimore corridor and sells ISP and cloud services under the DACS-NX and DACS Cloud names. ARIN registered the ASN in 2019, so despite the low number there is no early-internet pedigree here.

What it's used for

• Routed ISP and cloud addressing, not the exchange fabric itself. The announced /24s carry netnames SPG-ISP-REASSIGN-BLOCK1 and BLOCK2 registered to DACS Cloud, which is customer-reassignment space.
• Reverse DNS resolves to gateway routers under dacs-nx.net (for example a bwi1 gateway, i.e. the Baltimore–Washington area), confirming this is the operator's own transit and hosting network.

Notable

• The registered address is a Silver Spring, Maryland data-centre facility, and the company's exchange presence spans sites including Baltimore, Ashburn, Reston, Atlanta, Orlando and New York.
• Do not confuse this AS with the peering LAN. An IXP operator's company AS and its exchange fabric are different things; only the former originates routes, and that is what AS6515 does.

Interesting

• The registry has carried several names for this ASN over the years (DACSIX-EAST, DACSNX-ISP, DACSNX-APEX), reflecting the operator's split between its exchange, ISP and cloud brands.
