Bytespider (ByteDance)
ASNByteDance operates Bytespider (e.g. for Toutiao / search-related crawling). ByteDance does not publish a single English public IP feed — use ASN context below and verify live traffic.
Bytespider traffic is frequently observed from Amazon AWS (AS16509), not only from ByteDance’s own BGP origin (AS396986). Combine official webmaster guidance, live rDNS, and your traces - do not rely on ASN or static IPv4 lists alone.
