Dynamic IP
A dynamic IP address changes each time you connect to your Internet
Service Provider (ISP). This allows ISPs to keep a pool of addresses
available to subscribers. If you disconnect from the ISP, your address
is returned to the pool, becoming available to the next computer that
connects.
DNS
DNS stands for Domain Name Service. DNS servers translate names, such
as “yourname.com” into the numeric IP address that the Internet uses to
send and receive information. Most ISPs and companies run their own DNS
servers, and there are thousands of them on the Internet.
Domain Name
A domain name is a name given to an organization of computers on the
Internet. For example, “google.com” and “yahoo.com” are domain names.
Dynamic DNS
A process of performing an RFC 2136 “DNS Update” to add, modify or
delete DNS resource records on the fly without reloading the entire
DNS zone master file.
Ethernet
Is a protocol that is very commonly used in computer networks.
Fully Qualified Domain Name (FQDN)
A Fully Qualified Domain Name is the combination of a hostname and a
domain name, with the hostname being to the left of the domain name. For
example: “www.google.com” and “www.yahoo.com” are fully qualified
domain names.
File Transfer Protocol (FTP):
An Internet protocol designed for the purpose of a client downloading
files from an FTP server. No-IP.com does not provide FTP space but our
users are encouraged to run their own FTP server.
Hostname
A Host or Hostname is a textual name given to a computer. A computer
can have more than one name. Common hostnames are “www”, “mail” and
“ftp”, but you can name a host just about anything.
Hyper Text Transfer Protocol (HTTP)
HTTP is the standard protocol used by web servers to transmit data back and forth to your browser.
Internet Protocol Address (IP)
The Internet Protocol (IP) address is assigned to your computer,
providing a numeric address necessary for connecting to the Internet or
another IP-based network.
Internet
The Internet is a large collection of computers that are inter-connected and using the TCP/IP protocol to communicate.
Internet Service Provider (ISP)
A company that provides individuals and other companies access to the
Internet and other related services such as website building and email
services.
Post Office Protocol (POP3)
Is an Internet standard protocol that is used to allow users to download their email to their computer from the mail server.
Port 25
This is the standard port that mail servers listen on. Many ISP’s
block inbound and outbound port 25 to stop spammers from abusing their
networks. This makes running a mail server on one of these ISP’s
networks nearly impposible. See Mail Reflector and Alternate-Port SMTP
for No-IP based solutions to get around this problem.
Port 80
This is the standard port that web(http) servers run on. Many ISP’s
have blocked port 80 to stop viruses such as Nimda from slowing down
their networks and infecting their customers computers. Use No-IP’s port
redirect or web redirect host type to get around this issue.
Root Nameserver (Root Server)
A root nameserver is a DNS server that answers requests for the root
namespace domain and redirects requests for a particular top-level
domain to that TLD’s nameservers.
Registrar
A Registrar is the company or organization that you purchased or registered your domain name through.
Static IP
A static IP address is fixed, much like a telephone number. If
your ISP gives you a static address, you will always use the same
address. Servers usually have static addresses, so they can always be
found at the same location.
Simple Mail Transport Protocol (SMTP)
This is an Internet standard protocol that is used to send outgoing email over the internet to an email (SMTP) server.
Spam
Spam is unsolicited bulk or junk email.
Top Level Domain
The highest level in the Domain Name System hierarchy. The portion of
the domain name that comes after the dot “.” (.com, .net, .org, .uk).
Terms of Service (TOS)
No-IP’s terms of service agreement can be viewed
here.
Universal Resource Locator (URL)
A URL is a way to specify the location of somthing found on the
Internet. A URL typically points to a website and appears as a link on
web pages.
Web Redirect
Also known as HTTP Redirect or URL Redirect. Replace a long url with
an easy to remeber shorter one using a web redirect.
http://www.somefreeisp.com/community/pages/members/some_page.html
becomes http://mypage.no-ip.com/
