About this network

An internet exchange point. DACS-IX operates a multi-region peering fabric in the United States, with its registered address at 12401 Prosperity Drive, Silver Spring, Maryland. This AS is one of several DACS-IX carries, covering one of its regional fabrics.

What it's used for

• Exchange infrastructure: peering LAN, route servers and management systems for DACS-IX subscribers, who connect at sites across the eastern and other US regions.
• Announces a single IPv4 /24 (199.59.210.0/24) alongside a set of 2602:ffa9::/48 IPv6 blocks. Reverse names resolve under dacs-nx.com.

Notable

• An IXP is not a hosting, transit or access network. The addresses here exist so that member networks can peer with each other; almost none of the traffic an exchange enables is addressed to the exchange's own space.
• The tiny announced footprint relative to the AS's importance is normal for an IXP, whose value is in the fabric, not the address inventory.
• ARIN records show the current assignment of this number dating to January 2025, so the low AS number is a reissue of a recycled number rather than an early-internet allocation. Do not read AS7124's pedigree from its digits.
