AS608

AS608 has no live registration today. Direct queries against ARIN's RDAP endpoint (rdap.arin.net/registry/autnum/608) and its classic Whois-RWS REST endpoint both return HTTP 404 — the autnum record has been removed or reclaimed, not merely slow to resolve, and this was confirmed independently across two separate research passes. RIPEstat's as-overview data call shows an empty holder string for the resource, and IP2Location independently lists the ASN as "Unassigned" with zero allocated address space. AS608 also carries no current routing footprint: RIPEstat shows announced=false, zero prefixes in the current announced-prefixes window, and zero of 327 (v4) / 322 (v6) RIS peers observing it. Its last appearance in the global routing table was 2011-10-05, originating 68.179.248.0/22, the tail end of a small run of IPv4 blocks in 68.179.0.0/16 first seen 2009-08-11 with a single observed BGP peer, AS22561 (CenturyLink Communications, LLC) — a footprint consistent with a small regional access ISP rather than a transit or content network. A historical operator name, "BUFORD-COMM-ALLIAN-1 / Alliance Communications Network," surfaces in third-party AS-name-list scrapes and general web search, but no primary ARIN source (live record, Wayback-archived RDAP/whois snapshot, or ARIN org-name search) could corroborate that attribution — it is recorded here as a sourced, unconfirmed lead rather than fact. No public abuse signal was found for AS608 in Spamhaus's ASN-DROP list or its dormant/resurrected-ASN report, nor in NANOG mailing-list archives.

Operator

Unconfirmed. No live ARIN registration exists. Third-party AS-name-list mirrors and an FCC filing search point to a historical "BUFORD-COMM-ALLIAN-1 / Alliance Communications Network" (possibly Buford Communications I, L.P. d/b/a Alliance Communications Network), but this could not be corroborated against any primary ARIN source — no Wayback-archived ARIN whois/RDAP snapshot exists, and an ARIN org-name search for either name returns zero results [Likely, third-party-sourced only] — https://www.bgplookingglass.com/list-of-autonomous-system-numbers, https://ipinfo.io/AS608, https://www.fcc.gov/document/buford-communications-i-lp-dba-alliance-communications-network

Country / RIR

US, ARIN [Likely] — RIPEstat as-overview block "Assigned by ARIN"; historical announced space (68.179.0.0/16) is ARIN-administered space

Allocated

Unknown — the ARIN RDAP autnum record no longer exists. Direct fetches to rdap.arin.net/registry/autnum/608 and whois.arin.net/rest/asn/AS608.json both returned HTTP 404 (confirmed independently by two research angles across three attempts), so no top-level events[] block could be read and no registration date can be recorded. A third-party mirror (ipinfo.io) surfaces "2009-07-22," but that is not a first-party RIR RDAP date and was explicitly flagged as unreliable for this field by the angle that found it

[Unknown] — https://rdap.arin.net/registry/autnum/608, https://whois.arin.net/rest/asn/AS608.json

Org status

REVOKED/RECLAIMED — no current ARIN registration record; live RDAP and Whois-RWS both return 404; RIPEstat holder field is empty; IP2Location independently reports the ASN "Unassigned" [Confirmed] — https://rdap.arin.net/registry/autnum/608, https://www.ip2location.com/as608

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-07-16 — absent from Spamhaus's full ASN-DROP list and its dormant/resurrected-network report, and no NANOG archive threads reference it. Dormant ASNs are themselves a known hijack/resurrection risk category per Spamhaus's own reporting, though no specific incident ties to AS608 [Confirmed for absence-of-signal; Likely for the general risk framing] — https://www.spamhaus.org/drop/asndrop.json, https://www.spamhaus.org/resource-hub/threat-intelligence/suspicious-network-resurrections/

Network & routing

Network type

historically a small regional access/residential-ISP footprint (single observed peer AS22561/CenturyLink, six small IPv4 blocks in 68.179.0.0/16); no current network — the ASN has been unrouted since 2011-10-05 [Likely] — RIPEstat routing-status, https://bgp.he.net/AS608

Size

0 current IPv4/IPv6 prefixes and addresses; historically peaked at 68.179.248.0/22 (1,024 addresses) as of the last BGP observation on 2011-10-05 [Confirmed] — https://stat.ripe.net/data/routing-status/data.json?resource=AS608

Routing/peering

not announced; 0/327 v4 and 0/322 v6 RIS peers seeing it; 0 observed neighbours; no PeeringDB network record exists for AS608 [Confirmed] — RIPEstat routing-status

RPKI

not assessable — 0 announced prefixes means there is nothing to validate; RIPEstat's rpki-validation call requires a specific prefix argument, which is moot here [Unknown]

Notable usage

none currently. Historically originated 6 small IPv4 blocks between 2009-08-11 and 2011-10-05 with one observed peer, AS22561 (CenturyLink Communications, LLC) [Confirmed] — RIPEstat routing-status, https://bgp.he.net/AS608

Related ASNs

none identified

Analyst note

one angle (community research) treated the current MN/SD/IA fiber cooperative "Alliance Communications" (alliancecom.net) as the same entity behind historical AS608, while another angle explicitly could not verify that link (no primary-source corroboration). Do not conflate the two without further evidence.
