Summary
SEI Data (SEI Communications)
isp legacy
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.comandmx2.seidata.com, while the bulk of the space is subscriber pools of the formCODE.jv.pool.seidata.comandCODE.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.

Interconnection

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-25, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,779 prefixes, as published 2026-10-24. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
