Folks these days around the world are using internet to an extent they can’t live without it. They’d rather quit brushing their teeth & take bath. Sad but true.
Well my intention is throw some light on the concept of “STATIC IP ADDRESS & DYNAMIC IP ADDRESS”
First of all is it necessary to have two of them? Well of course technology ain’t dumb enough to stress for nothing.
Basically IP (Internet Protocol) provides set of basic rules to be followed while communicating. Here IP address is the address given to each computer, precisely the Ethernet card in the LAN. Hence it’s a way to recognize the machine.
Static IP address is like your name. It stays same or is permanent. Well unless you change your name for some corny reasons.
You configure the machine with that static IP address once for all. It won’t change at all. So it’s like the machine name & the DNS name stays same. You’ll be stuck with the same name forever.
Now what’s DNS?
DNS (Domain Name System) is system where in a hierarchical method of naming is given for all the stuff related to internet. Be it application, service or machine itself. Hierarchical in sense relative to it’s origin, which is meaningful. Like you , your father, your country etc. DNS keeps track of all the information like the domain, sever name & related stuff. For example a list of mail servers to accept emails.
In common words DNS matches host & it’s IP. Take for instance you read a website as name eg www.ironmaiden.com but the DNS will give it a name something like 192.56.1.35.
Results.vtu.ac.in makes sense with the hierarchical naming.
Static IP makes the access faster than dynamic IP, but it shucks as new LAN machine needs reconfiguration & gets you indulged in the blues again!
Dynamic IP
The IP were limited in number, since they represented finite numbers. A new approach by our beloved scientists working their sweat off proposed dynamic IP address.
Dynamic IP addressing takes help of DHCP! Now what in earth is this DHCP?
Well I tell you what.
Dynamic Host Configuration Protocol as the name suggest is meant for a computer which requests for an IP address from a pool of IP address.
From these pool of IP address, a temporary IP address is selected & this IP address is the dynamic IP address. The allocation of Dynamic IP can be done either in
Dynamic allocation –Where a DHCP machine requests for an IP & based on best features for that client the IP address available is given.
Automatic allocation-Where a free IP available is allotted. It probably would be the previously held IP address.
Dynamic IP address are like temporary pass. After a valid time a new IP address is generated. Dynamic IP address are configured too. It’s not like nobody can trace as it keeps changing! You might notice in your gmail account about the details of IP addresses used during the session. For a dynamic IP address it keep track of all the IP addresses that were used. Generally the starting numbers of the address’d be same which states the DNS hierarchical structure.
To add up security from unauthorized server to use up all the IP address pool, authenticated servers only are allowed, but you know hackers would find another way out!
Dynamic IP addressing is what going on nowadays & it’s cool because new LAN can be automatically configured. And you don’t have worry about configuring! Just pin it & ride on!
But …………there’s a thing. What if there’s no IP address available in the pool for you?
Answer: You get whooped! It’s show an error saying limited or no connectivity in your network connections!
So Dr.Deadly what do I do!
I’d recommend to restart the modem or wait! If nothing works well………restart & wait!
There’ll be a IP address soon meant for you!
