AS719

AS719 is an actively-routed Finnish national ISP ASN, registered under RIPE NCC to Elisa Oyj, announcing roughly 152 IPv4 prefixes and 5–6 IPv6 prefixes with full route-collector visibility (328/328 RIS peers on IPv4, 324/324 on IPv6). Despite its low three-digit number, it is not an ARIN-region legacy relic — an ARIN RDAP query for AS719 redirects to RIPE's RDAP service, confirming RIPE NCC as the authoritative registry, and the ASN has been continuously routed since it was first seen in 2000.

The AS name traces a chain of Finnish ISP consolidations: originally EUnet Finland Backbone AS, later Kolumbus and Saunalahti Group, then Jippii Group and SciFi Communications International, before settling under Elisa Oyj. PeeringDB's notes field explicitly flags the old AS-KOLUMBUS AS-SET as "no longer maintained," confirming that lineage is retired and AS719 today is simply Elisa's ASN.

Routing scale is substantial for a national incumbent: CAIDA ranks it 657 globally with a customer cone of 67 ASNs, 450 prefixes, and roughly 4.33 million addresses, and RPKI adoption is strong — 128 valid ROA-covered origins (122 IPv4, 6 IPv6) with zero invalid signatures observed. The only BGP relationship visible in third-party looking-glass data is AS6667, which itself resolves to Elisa Oyj, so no genuine external transit provider could be confirmed from public routing data alone.

Elisa Oyj is a public company listed on Nasdaq Helsinki, Finland's telecom market leader with roughly 140 years of operating history, 2.8 million-plus customers across Finland and Estonia, EUR 2.3 billion in 2025 revenue, and 6,200-plus employees across 35 countries.

Abuse signal

No notable public abuse signal found as of 2026-07-25 — AS719 is absent from the Spamhaus ASN-DROP list (417-record asndrop.json checked) and ipinfo.io's AS719 reputation page shows no warnings.

NANOG history

Archive search for "AS719" returns only routine automated CIDR Report postings (1996–2004) about route-aggregation efficiency, not abuse or hijack discussion.

Verification gap

AbuseIPDB's per-ASN page and Cisco Talos reputation lookup both failed to load (404 and 403 respectively) during this check, so those two sources remain unverified rather than confirmed clean.

RPKI posture

Strong — 128 valid ROA-covered origins and 0 RPKI-invalid announcements, reducing route-hijack risk for prefixes originated by this ASN.

Upstream ambiguity

The only observed BGP relationship (AS6667) is itself Elisa-operated, so genuine third-party transit exposure could not be independently assessed from public data.
