For years, we have heard of the depletion of IPv4 address space on the Internet. At the same time, more and more networks are coming online. Out of these new networks, we have an ever-increasing number wanting to participate in BGP routing. This can be for several reasons. The first is for what BGP was designed for autonomy. Companies are not at the mercy of a single provider for critical infrastructure. If you have ever had to switch providers with IP addresses from...

Border Gateway Protocol (BGP) is the Internet’s dominant inter-domain routing protocol, and as such, it is a critical component of the Internet’s infrastructure. However, BGP, like any other technology, has flaws. The following are some of the most common BGP issues: Some of the above issues are being addressed with RPKI, Routing Registries, and MANRS, to name a few.

Ever wonder why BGP seems to be such a complicated protocol to administer? It seems pretty straightforward to set up. Some commands, and you have a BGP session. Easy huh? BGP is one of those things where the more BGP feeds you bring in, the more complex traffic management becomes. Why? Take a look at the following graphic. What you are looking at is a small visualization of some of the AS connections to Hurricane Electric (AS6939) in North America. This is not...

APNIC has a bog article on detecting “bgp lies”. https://blog.apnic.net/2021/05/24/a-tool-to-detect-bgp-lies/Do you ever wonder whether you can really trust other networks, such as your provider(s) and peers? More precisely, wouldn’t you like to be able to tell if the traffic you send always flows through the paths received in the Border Gateway Protocol (BGP)? Could it be that, for some prefixes, the forwarding path might differ?

I am starting to see the following scenario more and more as IPv4 space is hard to get, but isn’t. With ARIN it is still possible to get an IPv4 allotment. Many smaller ISPs qualify for a /24 and can get one if they wait long enough on the ARIN waiting list. a /24 of IPv4 space is the smallest block that 99% of the Internet allows to be advertised on the Capital I Internet. There are filter rules in place that drop...
