About Me

who am i?

I'm a Korean developer who loves working with the user-oriented project.
And I'm motivated by a need to create actually what I need in my real-life. (see my works)
I worked as a developer for micro hardware and massive network applications.

Now I am a mobile network engineer, I mean, dealing with LTE network issue or IP Router problem so on.
For example, one of my jobs is "Traffic Engineering" which is predicting how it will grow next month to total traffic on MPLS backbone network capacity of "cell phone" and managing capacity operation (including some optical WAN lines and configuration to Routers and Switches).

It is great experiences to me work in Mobile Network Operating Company at Network dept, because now I can fully understand how LTE works end to end! there are a lot of ppl who know how tcp or Linux socket works but very few lte network works.

So my interest has changed so much, from something for server or application to something for Internet service provider or data center.
Now I am interested in SDN(software defined network), MPLS, Virtualization, DPDK(Dataplane DevKit), and 5G Networks.

what is my Public IP?

Simply show your ip. Sometimes you want to know IP address what you are actually doing with.

Use with curl. If you use VSN, or Dynamic IP, it's annoying to find out whenever your public ip're changed.

Just type like this on your terminal.

teemo@ubuntu:~$ curl ip.teemo.io
