AS15

AS15 is a legacy/experimental allocation registered under ARIN to "DYNAMICS," and it is the SRI/DARPA-era experimental "NET DYNAMICS EXP" (Network Dynamics) allocation — not Digital Equipment Corporation, which is a widespread folklore error. RFC 1020 (November 1987) lists it verbatim as "15 NET DYNAMICS EXP [ZSU]," and RFC 923 records that IANA originally assigned the 128.64–128.79 space to "Net Dynamics Exp," contact Zaw-Sing Su of SRI; the current ARIN POC ZSU-ARIN is the same SRI internet pioneer (co-author of RFCs 810, 819, and 830). The DEC association is not supported by any authoritative source: DEC's genuine early ASN was AS33 (DEC-WRL-AS, Digital Equipment Western Research Lab) per RFC 1020, and DEC's Class-A holdings were network 16 (DEC-INTERNET) per RFC 1166 — so the DEC→Compaq→HP→HPE corporate lineage is irrelevant to AS15. The ASN is fully dormant: zero IPv4 and zero IPv6 prefixes, no upstreams, no peers. The ARIN ASN RegDate is blank (only "Updated 1991-06-27"), so the original assignment date is unknown. For analysts this is a registered-only relic of 1980s DARPA experimentation expecting no live routes; do not attribute it to DEC/HP/HPE. No notable public abuse signal was found as of June 2026.

Notable usage

SRI/DARPA experimental "NET DYNAMICS EXP" allocation. RFC 1020 (1987) lists "15 NET DYNAMICS EXP [ZSU]"; RFC 923 records IANA assigning 128.64–128.79 to "Net Dynamics Exp," contact Zaw-Sing Su (SRI). NOT Digital Equipment Corporation — datatracker.ietf.org/doc/html/rfc1020

Related ASNs

none. NOTE: DEC's genuine early ASN was AS33 (DEC-WRL-AS); DEC's Class-A was network 16 (DEC-INTERNET) per RFC 1166 — AS15 has no DEC linkage [Confirmed via primary RFCs]

Analyst note

A registered-only relic of 1980s DARPA experimentation; expect no live routes. Do NOT attribute AS15 to DEC/HP/HPE — that is a folklore error and the most important correction in this batch.
