Hostname

A hostname is the unique name that will identify your computer. Pick something you will remember, such as yourname.serveftp.org.

Host Type

DNS Host (A): This is the most common choice. It maps your hostname to an IP address.

DNS Host (Round Robin): This maps your hostname to multiple IP address. Only used for DNS based load balancing (not common).

DNS Alias (CNAME): This maps your hostname to another hostname. It is useful for pointing many hosts to the same place and updating them easily.

Port 80 Redirect: Port 80 redirects are used to get around ISPs that block inbound port 80. By using the this and running your webserver on an alternate port users can access your site without having to enter the port number in the url.

Web Redirect: This maps your hostname to a URL. Web Redirects only work for HTTP and cannot be used to remotely access your computer.

Port 80 Redirect

Port 80 Redirect: Port 80 redirects are used to get around ISPs that block inbound port 80. By using the this and running your webserver on an alternate port users can access your site without having to enter the port number in the url.

Web Redirect

Web Redirect: This maps your hostname to a URL. Web Redirects only work for HTTP and cannot be used to remotely access your computer.

IP Address

An IP address is a number that identifies your computer on an IP network like the Internet. E.g., 204.16.252.98.

Wildcard

A wildcard makes all subdomains resolve to the same record as the parent. So if you enabled wildcard for wc.example.com, anything.wc.example.com would resolve to the same address as wc.example.com without explicitly creating that host. This is useful if you want to set up many virtual hosts for your personal web server.

This option is always enabled for Basic DNS service domains.

Advanced Records

TXT: A Text (TXT) record is an extra DNS record that can be used to attach information to an address. The most common use for TXT records is to implement SPF (Sender Policy Framework) and DKIM records which describe what mail servers are allowed to send email for your host or domain.

SRV: An SRV record describes services offered by a host. It is commonly used in SIP and XMPP protocols.

Special Clients: Some camera and DVR device manufacturers support mac address to No-IP hostname associations. If you own one of the supported devices you may associate your hardware device to a single No-IP hostname in your account.

Domain

Enter the domain name to be registered. Exclude www before the domain. ie yourdomain.com.

# Locations

The number of different IP addresses that will be associated with a round robin hostname. This can be changed later.

Location

By entering a label for each round robin IP address you will be able to distinguish each in the dynamic update client and only update the appropriate one.

CNAME Target

The target host is a hostname that the host you are creating resolves to. This host must be an actual hostname that resolves to an IP address.

Redirect Port

This should be set to the port you have your webserver running on. The port should also be opened or forwarded on your firewall or router.

Redirect URL

This is the location to which your hostname will redirect. For example, postsecret.blogspot.com/

Offline Settings

When the host is put into offline mode the selected action will be performed.

Offline IP: The host will resolve to this IP address.

Web Redirect: The host will redirect to this URL.

Offline Page: This page will be shown.

No Action: No DNS change will take place, of course.

Go Offline Now

If this is checked when you click the Update button, your host will immediately go into offline mode.

Mask URL

If checked the browsers location bar will show only your hostname, not the page they have been redirected to. This is done with a frameset.

Mask Page Title

If Mask URL is enabled, you can use this option to set the title of the page that will be seen at the top of the browser or when the page is bookmarked.

Mask Meta Keywords

If Mask URL is enabled, a meta tag containing the supplied keyworks is added to the header of the page to aid in search engine optimization.

Mask Meta Description

If Mask URL is enabled, a meta tag containing the supplied description is added to the header of the page to aid in search engine optimization.

MX Records

MX records are attached to a hostname to tell email server where email for that hostname should be delivered. The email server will try each hostname according to its priority in order until it finds one that responds.

MX records must be hostnames that resolve to IP addresses. Do not use a CNAME!

Host Groups

By assigning hostnames to a group the entire group can be updated to the same IP address. Passwords can be assigned to groups to create subaccounts.

Logged in as...

This shows the username you are currently logged in with, and the IP address from which you are connecting to No-IP.com.

DKIM, or DomainKeys Identified Mail, is an email authentication method that uses a digital signature to let the recipient of an email know that the message was sent and authorized from the domain;
