About this ASN.
AS57 is a legacy allocation registered under ARIN to the University of Minnesota, and it is used in connection with the Northern Lights GigaPOP, a regional research-and-education aggregation point. The RADB routing object lists as-name "NL-GIGAPOP" with the description "Northern Lights GigaPOP" and the remark "Operated by: University of Minnesota," maintained under MAINT-AS217. Potaroo's legacy-autnums mirror records the original RFC 1166-era label as "UMN-REI-UC — University of Minnesota," confirming continuous University of Minnesota tenure from the 1980s to today. It is actively announcing 4 IPv4 prefixes and 1 IPv6 prefix and appears as a member of the regional R&E peering AS-sets (AS-NLG-PARTICIPANTS / AS-WISCNET-WRIPS). The ARIN RDAP RegDate is 1985-12-18. For triage this is a live academic and regional-R&E ASN, encountered as Minnesota higher-education and Northern Lights GigaPOP infrastructure. No notable public abuse signal was found as of June 2026.
