Advanced users may be interested in how Silktide downloads pages from their website, for example to open up firewalls if connections are overloaded.

IP addresses

The servers which Silktide uses to download webpages are hosted by Amazon Web Services (AWS). These servers use a large dynamic range of servers around the world.

You can review AWS current list of IP ranges. Generally we recommend filtering by User Agent, rather than IP, as the latter is expansive and more volatile.

User Agent

Silktide imitates the user agent of the devices that it is testing, such as a Windows desktop computer or an Apple iPhone. However, it also adds a customizable suffix to the user agent, which by default is Silktide.

You can customize this suffix, or remove it entirely, under Settings > Website settings > Advanced > User agent.
