BGP.Tools: Browse the Internet Ecosystem
- dapperdrake 1y agoThis tool looks really good. It seems like soon ASN level bot-curbing will become common.
- RGBCube 1y agoIt is really good for blocking whole Chinese & LLM scraper ASNs!
- ranger_danger 1y agocidr-report.org has been around for over 20 years, curious why you think this site now will make a difference with blocking bots?
- supriyo-biswas 1y agoMost people don't know about it; in fact most of the IP geolocation providers pull their data from cidr-report.org or thyme.apnic.net.
- zinekeller 1y agoI'm not shocked. ASN blocking is well-known among people who I can easily called experts (veterans which can set up a reasonable-ish firewall from base principles) and ASN control is exposed in major cloud firewalls, but younger people (except those who were trained with deep networking skills) don't really understand ASNs for some reason.
- TheBoozyGenius 1y agoPretty zany.
- ddtaylor 1y agoA while ago there was a large data center outage that effected a lot of popular services and I speculated it might have been BGP, but it wasn't. During that time I was trying to learn BGP on-the-fly enough to know if this was a thing and I didn't have a lot of luck. What are some good methods or tools to know if BGP is causing a large scale outage before other experts have reported it?
- dgl 1y agohttps://radar.cloudflare.com/routing https://radar.cloudflare.com/routing might be of interest for aggregated data that doesn't require a complete understanding of the internet. The global looking glass that bgp.tools has is pretty powerful too, but it gives you a lot of data, so if you don't know what you're looking for or what it should look like it's hard to say something is wrong.
- Hikikomori 1y agoIts usually not BGP, its some operator misconfiguring BGP, and there's loads of ways of doing that and its hard to know what that would look like from a remote view like your own network. Most efficient way is to just compare current bad state to previous good state and look at the diff, ie what changed for some prefix in your table compared to previous version of your table.
- rumblefrog 1y agoI find the map the most interesting map: https://map.bgp.tools/ https://map.bgp.tools/ And did not know Mercedes holds such a large block (53.0.0.0/8), and it appears to be mostly dark or unused.
- nocoiner 1y agoJust a fascinating map. Like looking into Neuromancer’s cyberspace. Is there a legend of what the different colors mean?
- mike_d 1y agoThe map also does a good job showing why we need to do away with multicast/class E and reuse the address space.
- kortilla 1y agoYou can’t use multicast because multicast addresses work today on private networks
- doughecka 1y agoLol, then what do we do with all the multicast traffic?
- ranger_danger 1y agoSurely something from https://en.wikipedia.org/wiki/Reserved_IP_addresses https://en.wikipedia.org/wiki/Reserved_IP_addresses could be repurposed?
- teaearlgraycold 1y agoHoly cow. Didn’t realize there is an entire /4 reserved for future use.
- yardstick 1y ago240/4 can be hijacked/used as private IP space currently by a lot of devices. I think Windows might be the hold out. But for internal routing and IoT it’s very useful. Can never be used as publicly routable space. I’d like to see it added to the official list of private space alongside RFC1918.

- j4nek 1y agobgp.tools is one of my most used sites - thanks to ben for doing this so great!
