PeeringDB 备注
ISC operates the F-Root nameserver in 70+ locations around the globe. Peering with ISC will make your DNS faster and more robust. We require you honor the well-known BGP community: "NO_EXPORT".
This ASN (3557) is used for sourcing the F-Root Anycast prefixes. Peering is available with the local ASN active on your IXP. Due to a change in PeeringDB's DB structure in Q1/2020, you can only find them in the organisation object, https://www.peeringdb.com/org/1330
