Dynamic DNS Most users with an internet connection also have a dynamic IP, no matter which provider they use. And if you do not know what you have, you probably use a dynamic IP because those who have a stable IP pay more than ordinary mortals and logically do not know about it.
Και για όσους δεν γνωρίζουν του όρους ip, dynamic, stable, σας αναφέρουμε ότι κάθε σύνδεση στο Internet χαρακτηρίζεται από ένα code number of the form xxx.xxx.xxx.xxx, where x is any number from 0 to 9. It is something like the number ID cardς καθενός από μας. Κάθε σύνδεση έχει διαφορετική IP για κάθε χρονική στιγμή. Βέβαια κάποιοι συνδυασμοί αριθμών δεν απαντώνται στις ips, καθώς επίσης και η εμβέλεια των ips που έχει η κάθε χώρα είναι συγκεκριμένη αλλά αυτά δεν μας αφορούν σήμερα. Το αναφέρουμε κυρίως για τυχόν επικριτές επί της ακριβολογίας του λόγου μας.
Each user can have a static IP (stable ip) connection, that is to have a specific combination of numbers that will never change and always represent the same specific user. This exclusivity costs a little more and raises the value of the monthly cost of your internet connection and that's why it is only preferred by professionals of the kind. While dynamic ip (dynamic ip) is this connection where your provider provides you with a random ip each time you connect to the internet through a range of available ips that you have and who can change it whenever and as many times as you want without informs you.
However, there are cases where you wish to connect remotely to your computer, either with the well-known Windows application, remote desktop with, or with another program of your own, such as a vnc, or ftp, or even make your computer a server so that someone can connect with you automatically.
Nice so far but how can this be done if your ip is constantly changing? Your friend will not know what ip to write to connect to your system since your ip can change numbers at any time. The solution to this problem is usually given by the routers (router), ie the box with the bulbs that we have at home and it has been provided to us by the provider with whom we have a contract. And we usually say because most of these devices support dynamic operation dns.
All you have to do is connect to your router through a browser (usually the routers have an 192.168.1.1 or 192.168.0.0 or 192.168.1.254, etc. The exact number can be found in your router's instruction booklet).
Look for a point in your router menu that is referred to as "dynamic dns". It may be under the tools submenu or something related. Unfortunately each router has its own special menu and we can not fully inform you about the route to follow until you find the point that interests us.
Στο dynamic dns θα δείτε ότι ο δρομολογητής σας έχει έτοιμα πεδία στα οποία μπορεί να δεχθεί επιλογές που αφορούν services του διαδικτύου που ειδικεύονται στις δυναμικές ips. Ο δικός μας, πρόκειται για ένα router μάρκας Thomson μας δίνει το δικαίωμα να συνδεθούμε κατευθείαν με μία από τις υπηρεσίες dyndns, statdns, no-ip, DtDNS, gnudip as well as a custom, one off list that we will set it up for ourselves.
Οι παραπάνω υπηρεσίες οι οποίες άλλες είναι επί payment και άλλες εντελώς δωρεάν (όπως οι no-ip, DtDNS) κάνουν το εξής:
- Κάθε φορά που αλλάζει η ip μας το router μας αφού πρώτα συνδεθεί με το internet και πάρει την νέα ip στη συνέχεια επικοινωνεί με την service που του έχουμε ρυθμίσει και της αναφέρει ποια ip έχει την συγκεκριμένη χρονική στιγμή.
- Η υπηρεσία αυτή έχει φροντίσει να δεσμεύσει για εμάς ένα domain name του τύπου iguru.kapoio-domain.com. Φυσικά έχουμε πρωτίστως κάνει εγγραφή στην εν λόγω υπηρεσία και έχουμε επιλέξει ένα name domain that we like and can remember.
- The service each time corresponds to the domain that has been committed to us with the ip that has been declared by our router and so our friend has only to write domain iguru.kapoio-domain.com and connect to our computer.
This is a great convenience, so we know at any time that with a commonly memorable name we can connect remotely with our computer and this is done simply through our router, without having to run a similar program on our computer and only to connect with him.
Good Luck.
