The purpose of this article is to discuss an ethnography of code, specifically code ethnography, a method for examining code as a socio-technical actor, considering its social, political, and economic dynamics in the context of digital infrastructures. While it can be applied to any code, the article presents the results of code ethnography application in the study of internet interconnection dynamics, having the Border Gateway Protocol (BGP) as code and two of the largest internet exchange points (IXPs) in the world as points of data collection, DE-CIX Frankfurt, and IX.br São Paulo. The results show inequalities in the flows of information between the global North and the global South and concentration of power at the level of interconnection infrastructure hitherto unknown in the context of the political economy of the internet. Code ethnography is explained in terms of code assemblage, code literacy, and code materiality. It demonstrates the grammar of BGP in context, making its logical and physical dimensions visible in the analysis of the formation of giant internet nodes and infrastructural interdependencies in the circulation information infrastructure of the internet.

本文的目的是讨论代码民族志，特别是代码民族志，这是一种将代码视为社会技术参与者的方法，考虑到数字基础设施背景下的社会、政治和经济动态。虽然它可以应用于任何代码，但本文介绍了代码民族志在互联网互连动力学研究中的应用结果，其中包含边界网关协议 (BGP) 作为代码和两个世界上最大的互联网交换点 (IXP)作为数据收集点，DE-CIX 法兰克福和 IX.br 圣保罗。结果表明，在互联网政治经济的背景下，全球北方和全球南方之间的信息流动存在不平等，以及在互连基础设施层面的权力集中，这是迄今为止未知的。代码民族志是根据代码组合、代码素养和代码重要性来解释的。它在上下文中演示了 BGP 的语法，使其逻辑和物理维度在分析中可见互联网流通信息基础设施中的巨型互联网节点和基础设施相互依存关系。
