The country shown for an AS number or an IP prefix is where it is registered, not where a server stands. Large networks announce the same addresses from many countries.
About GitHub
GitHub’s own network, used for github.com itself. GitHub Pages sites are served through a CDN, so they usually do not appear under this AS.
What it means when a site’s IP address is in this network
This network mainly carries GitHub’s own services. A third-party domain that resolves into it is normally using a product that GitHub hosts for customers (for example a pages, mail or storefront service) rather than a server of its own.
Check which network a domain is in
The IP lookup resolves a domain, then shows the AS number, prefix and network name of each address. Addresses in AS36459 link back to this page.
FAQ
Who owns AS36459?
AS36459 is registered to GitHub. The live box on this page shows the name, registry and allocation date as the registry data gives them at the moment of the lookup.
A website’s IP address is in AS36459. Is the site hosted by GitHub?
The address is in GitHub’s network, so the machine is most likely rented from GitHub. The site itself is run by the customer, not by GitHub.
How do I find the AS number of a domain?
Resolve the domain to its A and AAAA records and look up each address. OrbitProbe’s IP lookup does both and shows the AS number, the announced prefix and the network name for every address.
Does the country of an AS number show where the server is?
No. It is the country in which the number is registered. Networks announce addresses from many locations, and anycast networks answer from whichever site is closest to the visitor.
