Neptune Networks operates AS21700. We have an open peering policy.
Historically we have operated AS397143. This ASN is still in use both in public peerings and customer peerings but being phased out in favor of AS21700.
We have no requirements in terms of traffic, size, or support/SLA. We operate both IPv4 and IPv6 and appreciate peering with both protocols.
Please contact firstname.lastname@example.org to initiate peering.

We use large BGP communities for both informational and alterable communities.
These communities are available on both peer and customer prefixes.
|21700:101:1||Originated by Neptune Networks|
|21700:101:2||Learned from customer|
|21700:101:3||Learned from peer|
|21700:101:4||Learned from upstream|
|21700:102:840||Learned in the United States|
|21700:103:1||Learned in Neptune Networks' NY1 site|
When these communities are applied to prefixes received by Neptune Networks they alter their routing policy in our autonomous system. They are available only on customer BGP sessions.
Routes tagged with the blackhole community must be either an IPv4 /32 or an IPV6 /128 and have an encompassing IRR route or route6 object from an authenticated source like ARIN, APNIC, AFRINIC, or RIPE.
