IPv4 Looking Glass Sites, listed by ASN. (An IPv6 Looking Glasses page is also available.)
If you know of a working IPv4 Looking Glass site that isn't listed below, feel free to add it. (Don't have a wiki account yet? Sign up here.) Please only add sites that are true BGP looking glasses - pages that only allow ping and/or traceroute should not be included in this list.
Please correct any errors you find in this list. If a site is no longer responding, please change the “OK” in the Notes column to “FAILED” along with the date (mm/dd/yy). If the site becomes operational again, please change the “FAILED” message back to “OK”. If a site has been in “FAILED” status for over a month, it can be removed from the wiki.

Now that you've finished looking at this page, you may find the rest of the wiki interesting.
