The AS Name Search card on the home page said the search was coming
soon. It now asks the new GET /api/v1/search/as?q=<text>, which
searches the AS list built into asinfo, and lists the matches as links
to their AS pages. An empty q answers 400. asinfo.Search now ignores
case and returns its matches in AS number order. asinfo puts each
handle and description in lower case once, when the list loads.
A match can be an AS that the database has no record of. Its AS page
and /api/v1/as/{asn} then take its handle and description from asinfo
and still list its prefixes. They answer 404 only for an AS with no
record, no asinfo entry and no prefix. Empty prefix lists in that JSON
answer are [] rather than null.

Package asinfo provides information about Autonomous Systems (AS).
|
|
|
|
The package embeds a comprehensive database of AS numbers, handles, and descriptions
|
|
sourced from https://github.com/ipverse/asn-info. The data is embedded at compile
|
|
time and provides fast, offline lookups.
|
|
|
|
Basic usage:
|
|
|
|
// Get information about an AS
|
|
info, ok := asinfo.Get(15169)
|
|
if ok {
|
|
fmt.Printf("AS%d: %s - %s\n", info.ASN, info.Handle, info.Description)
|
|
}
|
|
|
|
// Get just the description
|
|
desc := asinfo.GetDescription(15169) // "Google LLC"
|
|
|
|
// Search the handles and descriptions, ignoring case; the matches come
|
|
// in AS number order
|
|
results := asinfo.Search("university")
|
|
for _, as := range results {
|
|
fmt.Printf("AS%d: %s\n", as.ASN, as.Description)
|
|
}
|
|
|
|
The data is loaded lazily on first access and cached in memory for the lifetime
|
|
of the program. All getter methods are safe for concurrent use.
