In computing, inter-domain is a term used to describe interaction between domains[disambiguation needed]. It is most commonly used in the fields of multicasting and routing between internets, or as a substitute for the term inter-server. The term is also occasionally used in chemistry, for example with regard to protein domains.
Internet protocols that are focused on inter-domain functions include: Border Gateway Multicast Protocol, Classless Inter-Domain Routing, Multicast Source Discovery Protocol, and Protocol Independent Multicast.
The opposite of inter-domain routing is intra-domain routing: Routing within a domain or an autonomous system.
