AS698

AS698 (ASN-UIUC-REGION-AS) is an actively routed autonomous system registered to the University of Illinois System, operated day-to-day by the Urbana-Champaign campus's Technology Services Networking group. It currently announces two IPv4 prefixes — 64.22.176.0/20 and 204.93.0.0/19 — plus the IPv6 block 2620:79:8000::/48, together covering roughly 12,288 IPv4 addresses. The ASN has been visible in global BGP tables since at least 2003.

ARIN's RDAP record shows AS698 was registered on 1990-08-13, with the record last updated 2022-02-23. The campus network, internally called IllinoisUIUCnet, reaches the wider Internet through the Inter-Campus Communications Network (ICCN, AS40387), the University of Illinois System's regional research-and-education backbone, which in turn peers with WiscNet, the University of Chicago, OARnet, and Internet2's Commercial Peering Service.

AS698 has no standalone PeeringDB listing of its own (peeringdb.com/asn/698 returns 404), and RIPEstat shows only a single observed BGP neighbor — consistent with AS698 riding entirely on ICCN/AS40387 rather than maintaining independent transit or peering relationships. Visibility is broad: 323 of 324 RIPE RIS peers see the IPv4 announcements and 320 of 321 see the IPv6 announcement. CAIDA ranks the ASN 16,995th globally; its customer-cone size could not be confirmed from the available data.

Network & routing

Network type

Education / Research-and-Education network; rides the Inter-Campus Communications Network (ICCN, AS40387) [Confirmed] — http://publish.illinois.edu/networking/about/

Size

2 IPv4 prefixes (64.22.176.0/20, 204.93.0.0/19; ~12,288 addresses), 1 IPv6 prefix (2620:79:8000::/48) [Confirmed] — RIPEstat routing-status / announced-prefixes

Routing/peering

single observed BGP neighbor (AS40387); AS698 has no standalone PeeringDB entry (peeringdb.com/asn/698 returns 404); the related AS40387/ICCN entry lists an Open peering policy [Likely] — https://bgp.he.net/AS698, https://www.peeringdb.com/net/7635

RPKI

no ROA coverage observed; bgp.he.net reports 0 RPKI-valid / 0 RPKI-invalid origins [Likely] — https://bgp.he.net/AS698

CAIDA rank

16,995 [Confirmed] — supplied CAIDA data block; customer-cone size [Unknown] — CAIDA block was truncated in the source data before cone/degree fields appeared

Notable usage

primary campus/institutional network for the University of Illinois at Urbana-Champaign, serving 450+ campus buildings; feeds ICCN's ~600-mile DWDM regional fiber ring (Champaign-Urbana, Springfield, Peoria, Bloomington, Chicago) at up to 100Gbps, which peers with Big Ten/CIC schools, Internet2, WiscNet, University of Chicago, and OARnet

Analyst note

Actively routed campus ASN, effectively single-homed to ICCN (AS40387), with no independent PeeringDB presence of its own; CAIDA customer-cone data was truncated in the supplied source and is recorded as Unknown rather than fabricated.
