Google has a liberal peering policy, subject to certain technical, commercial and legal requirements. To peer we ask for the following:

- a publicly routable ASN
- publicly routable address space (at least one /24)
- ASN record completed in PeeringDB
- 24x7 NOC contact capable of resolving BGP routing issues
- Presence at one or more of the 70+ Internet Exchanges, or 60+ private peering interconnection facilities listed here on PeeringDB
- Minimum traffic requirements as below

Peering Traffic Requirements (IPv4):
+ Peers in Europe with less than 100Mbps peak Google traffic can peer via the route servers at any participating European Internet Exchange
+ Peers in North America or Europe with more than 100Mbps peak Google traffic can peer via a bilateral BGP session over an Internet Exchange
+ Peers in Asia with at least 25 Mbps peak of Google traffic may peer via a bilateral BGP session over an Internet Exchange
+ There are no minimum traffic requirements for peers present at Internet Exchanges in Africa, and Central/South America
+ Private peering is welcome subject to sufficient traffic volume

IPv6 Peering: 
We welcome settlement-free IPv6 peering with any network that also has IPv4 peering with Google.

Routing Policy: 
In general, peering sessions with AS15169 will advertise all AS-GOOGLE routes. AS15169 interconnects in Africa and Asia may be limited to routes relevant to the respective region, and in some cases 'more specific' routes may be seen via a transit provider.  Web-indexing routes may only be seen over specific providers.

Traffic Management:
Google generally uses "cold-potato" routing, carrying traffic on our own network as close to users as possible. In general, Google recommends advertising all peer prefixes over all peering sessions with Google, unless other route advertisement policies have been agreed.

Maximum Prefix:
Suggested max-prefix of 1000 (IPv4) and 100 (IPv6)

Related ASNs: 
Google also manages the following ASNs:
AS36040, AS43515, AS36561
