About this network

SEIDATA is the internet network of SEI Data, Inc., the data arm of SEI Communications in Dillsboro, Indiana — a member-owned rural telephone cooperative serving several counties in the state's south-eastern corner.

What it's used for

• Consumer and small-business internet access across the cooperative's rural footprint, alongside the co-op's own infrastructure.
• Reverse DNS makes the split obvious: infrastructure sits on names like gw.seidata.com, ns1.seidata.com and mx2.seidata.com, while the bulk of the space is subscriber pools of the form CODE.jv.pool.seidata.com and CODE.sj.pool.seidata.com, where the middle label identifies the serving location.

Notable

• An eyeball network, not hosting or transit: roughly 24,000 IPv4 addresses, nearly all of it dynamic customer space, plus an IPv6 /32.
• The ASN was registered with ARIN in 1997, when a rural co-op getting its own BGP presence was still unusual; its oldest block, 206.162.192.0/19, dates from the same period.

Interesting

• Rural telephone cooperatives like this one are a distinctive feature of the US address landscape: small, independent, member-owned, and often holding legacy ASNs and address space out of proportion to their subscriber counts.
