ASN Lookup
Supports IPv4, IPv6, hostnames, full URLs, and direct ASN input like AS13335. For hostnames with multiple records, all resolved IPs are analyzed in one run. Each endpoint gets live BGP announcement visibility, route observability scoring, and RPKI route-origin validation, while direct ASN lookups now also return visible peer, upstream, and downstream topology so you can judge both routing breadth and network role without converting the ASN into sample IPs first.
