 Interested in becoming a regular contributor to Wikipedia? Create an account! Your may be shared by multiple users of an educational institution, so you might receive messages on this page that were not intended for you.

If you are unable to create an account due to your institution's IP address being blocked, follow these instructions. If you are autoblocked repeatedly, contact your network administrator or instructor and request that your school contact Wikimedia's XFF project about enabling X-Forwarded-For HTTP headers on its proxy servers so that blocks will affect only the intended user. Administrators: review contributions carefully if blocking this IP address or reverting its contributions. If a block is needed, consider a soft block using {{School block}}. In response to vandalism from this IP address, abuse reports may be sent to its network administrator for investigation.

Welcome! edit
Hello, and welcome to Wikipedia!
Someone using this IP address, 103.40.80.138, has made edits to Port (computer networking) that do not conform to our policies and therefore have been reverted. For more information on this, see Wikipedia's policies on vandalism and limits on acceptable additions. If you'd like to experiment with the syntax, please do so in the sandbox rather than in articles. If you did not do this, you may wish to consider getting a username to avoid confusion with other editors.
You don't have to log in to read or edit pages on Wikipedia, but creating an account is quick, free, requires no personal information, and has many benefits. Without a username, your IP address is used to identify you.
Some good links for newcomers are:
- Help contents – the main help page.
- Quick guide – a "cheatsheet" listing the main editing commands.
- The five pillars of Wikipedia
- Contributing to Wikipedia
- Tutorial
Please sign your name on talk pages using four tildes (~~~~); this will automatically produce your name and a timestamp. If you need help, check out Wikipedia:Questions, ask the Help Desk, or place {{helpme}} on your talk page and someone will show up shortly to answer your questions.

January 2022 edit
Hello. This is a message to let you know that one or more of your recent contributions, such as the edit you made to Hydroxylammonium nitrate, did not appear to be constructive and have been reverted. Please take some time to familiarise yourself with our policies and guidelines. You can find information about these at our welcome page which also provides further information about contributing constructively to this encyclopedia. If you only meant to make test edits, please use the sandbox for that. If you think I made a mistake, or if you have any questions, you may leave a message on my talk page. Thank you.
