Choose your DNS target
Our Unsere Points of Presence (PoPs) are organised into PoP Groups that provide certain features. In order to direct traffic at wao.io and to change your DNS accordingly, you have to choose among the following groups.
global.wao.zone.
Features: Geo Routing, Failover, DDoS ProtectionPoPs: Cologne, Frankfurt
This group contains all public PoPs, regardless of location. We plan to setup more PoPs around the world in the future. This group will contain all of them.
This is our recommended choice.
DNS-Konfiguration:
www.example.com CNAME global.wao.zone.
example.com A 62.216.162.9
example.com A 81.173.210.90
stricttls.global.wao.zone.
Features: Geo Routing, Failover, DDoS Protection, StrictTLSPoPs: Köln, Frankfurt
This group is hosted in the same locations as global.wao.zone. .However, StrictTLS (requiring at least TLS 1.2) is enabled.
DNS-Konfiguration:
www.example.com CNAME stricttls.global.wao.zone.
example.com A 62.216.162.10
example.com A 81.173.210.91
eu.wao.zone.
Features: EU Hosting, Failover, DDoS ProtectionPoPs: Cologne, Frankfurt
This group contains all PoPs that are hosted in locations in the European Union. Traffic will never be served by PoPs outside the EU. Future expansions inside the EU will be added to this group.
DNS-Konfiguration:
www.example.com CNAME eu.wao.zone.
example.com A 62.216.162.9
example.com A 81.173.210.90
stricttls.eu.wao.zone.
Features: EU Hosting, Failover, DDoS ProtectionPoPs: Cologne, Frankfurt
This group is hosted in the same locations as .eu.wao.zone.. .However, StrictTLS (requiring at least TLS 1.2) is enabled.
DNS-Konfiguration:
www.example.com CNAME stricttls.eu.wao.zone.
example.com A 62.216.162.10
example.com A 81.173.210.91
Considerations
For the moment, both global and eu groups effectively contain the same PoPs. The choice you make now is about future expansion: Do you want world-wide delivery or hosting in the EU?
Our CNAME targets (as shown in the examples above) perform failure detection. The IP address of an unhealthy PoP will be immediately removed from our DNS until it recovers. Within 5 minutes, no users will be directed to that PoP. The other PoPs will take over the traffic. This is called failover.
This feature does not work with A records! You must use CNAME for dynamic DNS based failover.
If you use a first level domain, such as example.com, you should configure multiple A records as shown in the examples above. Your DNS will usually serve all IP addresses in random order.
Therefore, we strongly recommend that you use www. as your primary domain and the +first level domain+ only as a Redirect Domain.
Note that wao.io has no IPv6 addresses to accept incoming traffic. Please remove all AAAA records from your DNS configuration for domains pointing to wao.io.
