Why is Skyscanner asking for a new range of IP addresses to be added to the allowlist / safelist?
Over 90 million travellers around the world trust us each month to help them find the best flights, hotels and car hire and we continue to grow. In order to ensure that we build your itineraries into our search results in a fast and reliable manner, we need to continually evolve our existing hosting infrastructure as well as deploying into more and more locations worldwide.
To support this continued growth, we will need to increase the number of source IP addresses that we can contact you from.
When do I need to have the new range added to my allowed list?
We will begin sending traffic via the new IPs in early November. Traffic levels will initially be small but will increase as we add additional services to new locations.
Why are you adding such a large subnet range?
This larger range allows us to double our global footprint with the addition of a single IP range: whilst we will be only be sending traffic from a small range of IP addresses within the subnet, we may change which IP addresses we actually use quite frequently as we grow our infrastructure and add new points of presence across the globe.
What if I can only include individual IPs on the safelist?
Whilst we may be able to provide a subset of IP addresses that we will send traffic from under normal conditions, this will be at the expense of reliability. During times of network disruption, we may need to change the source IP addresses that traffic is sent from at very short notice. Also, we may require to change the IP addresses we send traffic from during normal operation at relatively short notice as our infrastructure grows, so you would need to be able to update your firewall configuration reasonably frequently.
What if I cannot safelist your IP addresses?
Skyscanner also supports a variety of API authentication methods - please speak with your account manager to discuss the alternatives for integrating with Skyscanner.
Should I remove my existing safelisted IPs?
This an addition to the previously published list of IP addresses provided - please review and ensure you have the correct ranges. If you have been a long-standing Skyscanner partner, you may have old ranges that are no longer in use, so please do review your firewall or application configurations.
