IP stands for "Internet Protocol". It is one of the fundamental protocols that powers the internet. IP is how data is able to be routed to the correct destination - your computer is assigned an IP address, and when you need to get data back, that data gets sent to your IP address.

I still don't have any idea what this tag's supposed meaning is, nor what questions should be tagged with it.

Now, there's the ip utility which replaces ifconfig, but then the tag makes no mention of it.

What is the usage of the tag, if any?

If you look at the description of the tag, you can see that the network section is organized by protocols and IP is one of them. Questions should be tagged with if they are specifically related to the protocol and concepts relative to it. Topics relative specifically to and for which would be too broad are for instance, the routing table, the structure of an IP datagram, etc.

What I can see is that this tag is sometimes overused. For example, questions about DHCP should be tagged only . There is no need to also put even if the question is about IP addresses.

If we want to make a tag for the ip utility, it should be distinct from the existing tag. Perhaps ?

  • I'm probably the one who's been using the tag ip the most, and I confirm that this is what I mean by it. – Gilles Jul 28 '14 at 22:57

    Oh, and the ip utility from the iproute2 suite is covered by the iproute tag. – Gilles Jul 28 '14 at 23:07
  • Ok, so no need for ip-utility. I didn't know about iproute but its description is clear and unambiguous. – lgeorget Jul 29 '14 at 10:18
  • The IP tag wiki currently explicitly says "and IP addresses". I'll remove that. Should ip be v4 only, or should it include v6? – derobert Jul 30 '14 at 15:30
  • We have a separate ipv6, so I'm going to guess v4 only. Though never mind, we have ipv4 as well... – derobert Jul 30 '14 at 15:34
  • @Gilles we have an ipv4 and ipv6 tags, what's the difference and how they have to be used? – Braiam Jul 30 '14 at 19:57

    @Braiam ipv4 for questions that are specific to IPv4 and wouldn't apply to IPv6 without profound modifications. ipv6 dually. ip for questions that would apply (possibly with minor modifications) to both versions. The obvious, in other words. – Gilles Jul 30 '14 at 20:18
