Summary
ISPN Network Services
hosting managed-services email wholesale kansas
ISPN — Internet Services Provider Network — is ISPN Network Services of Lenexa, Kansas. Since 1994 it has sold managed internet services to other ISPs: hosted email, spam and virus filtering, hosted servers, network monitoring and diagnostics, and outsourced technical support for rural and independent broadband providers.
What it's used for
Running platforms on behalf of small ISPs that do not want to run them in-house. The reverse DNS is a direct sighting of exactly that: ns1.rbl.e-scout.net and ns2.rbl.e-scout.net. e-Scout is ISPN's own trademarked mail-filtering product, and rbl is the standard abbreviation for a real-time blocklist — these are the DNS servers that answer blocklist queries for the filtering service. Infrastructure hosts, in the operator's own product zone.
Notable
Classified hosting, in the platform-operator sense rather than the sell-a-VPS sense. RIS observes 2 IPv4 prefixes carrying 4,096 addresses (64.35.208.0/20 plus a /24 deaggregate) and 1 IPv6 prefix, 2607:5800::/32, behind 2 BGP neighbours. A single tidy /20, dual-stacked, two upstreams: this is a service platform, not an access network and emphatically not a carrier — a wholesale transit business would show peering in the hundreds, and ISPN's wholesale relationship with its ISP customers is contractual, not a BGP adjacency.
Interesting
ISPN is a good example of a category that is easy to misfile. Its customers are ISPs, and its name contains "Internet Services Provider Network", but it does not sell internet access — it sells the back-office machinery of an ISP. The address space carries its servers, not anybody's subscribers.

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 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
