Free DNS Services and DNS Servers
The Public DNS Service
This is one of the oldest and longest running free DNS services providing 2 name servers for your website. If you need a name server or two for your site, and don't wish to use your web host's name servers or pay for commercial DNS services, try this one. Managing your domain records require some expertise though, since they do not provide you an easy interface like some of the other free and commercial DNS servers. However, you really get to control nearly every aspect of your domain records. You can add A records, CNAME records, MX records and nearly everything else that can go into the name server records for your domain You can have unlimited number of domains here. Note: they rely on donor hardware and connectivity for their name servers.
Mydomain and MyDNS Domain Name Services
They provide free DNS services for your domain name, free email forwarding, free URL redirection for your domain (with or without cloaking/stealth, with path forwarding), free parking, the ability to change your MX records, A records, SOA records, etc.
Hammernode Static and Dynamic DNS
They provide free static and dynamic DNS services, as well as web redirection for your website. You can use the static DNS (virtual DNS mapping) on your own domain name. For dynamic DNS purposes, you will be given a subdomain name like yourname.hn.org. If you like, you can also configure URLs like www.hn.org/yourname/ to point to your existing website.
PowerDNS Express
The express version of their service appears to be free. There is little information about the services they provide, but presumably at minimum it allows you to point your domain name at a static IP address.
EveryDNS
EveryDNS provides static DNS services, dynamic DNS resolution, redirection of your domain name to an existing URL, etc. Although the service is free, they solicit donations to support their services.
DYNU Dynamic DNS Service
This dynamic DNS service will allow you to host your own website, FTP, email, telnet, chat server on your own machine. You get a subdomain name (yourname.dynu.com) and a small program which will inform the DNS server whenever you're online as to which IP address you're at.
CJB Dynamic DNS and Web Redirection
This was originally a free web redirection (offering URL redirection) service that has extended its service to provide dynamic DNS. Your subdomain name, whatever.cjb.net (in fact, *.whatever.cjb.net) will be directed to your website when it is online. The only problem with this service is its sluggishness and the frequent downtime.
24LINK Dynamic DNS
Most of the other dynamic DNS providers listed on this page allow you to change your dynamic IP address by either using a small utility that connects to their servers and updates your IP address, or requiring you to update your IP address manually. 24LINK provides you with a free web server which you can download and install on your computer. The web server will automatically update their records to point to your current IP address when you go online. You get an address like www.24link.com/yourname for your website. There are no ads on your site.
Yi.org Dynamic DNS and Web Redirection
Want dynamic DNS or web redirection? You get subdomains like yourname.whyi.org, yourname.yi.org, yourname.weedns.org, yourname.b0b.com which you can point to any IP address you like, and a URL (eg, yi.org/yourname/) which you can redirect to any URL.
DYNS Dynamic DNS Service
If you run a web server that has an ever changing IP address (such as one that is "live" only when you are online through an ISP that issues you a dynamic IP address), you'll like this free service. They provide you a hostname (as a subdomain of dyns.cx), which can point to an IP address that you can change through a program running on your computer. The other services provided by them include dynamic DNS for multiple hostnames pointing at the same IP address (eg, ftp.yourname.dyns.cx, www.yourname.dyns.cx, *.yourname.dyns.cx); web redirection, etc.
DynDNS
You can get up to 5 subdomain names like yourname.dyndns.org which you can redirect to either a static or dynamic IP address. Alternatively, they also provide URL or web redirection where you can get hostnames (subdomains of domain names like doesntexist.org, webhop.net, webhop.org, etc) that are redirected to your actual URL. I'm not sure if there are any advertisements imposed on your site when you use their web redirection service.
ZoneEdit
ZoneEdit allows you to get free DNS services for 5 domains, provided your domains do not get a lot of traffic (according to their FAQ, "a lot" means something like a million hits per year or 200MB worth of traffic per domain; note this is 200MB worth of DNS queries, not the bandwidth used by your web pages). You can also forward your email, park your domains, and run websites on your own computer with their dynamic DNS services.
No-IP Dynamic DNS, Static DNS for your Dynamic IP
No-IP offers you Dynamic DNS so that you can run your websites from your own computer. They also provide you with a short hostnames (like yourname.hopto.org) that you can redirect to your existing website, ie, URL redirection. They also redirect email sent to you@yoursite.no-ip.com to up to three email servers/addresses of your choosing.
DNS Made Easy
If you use the domains provided by them (ie, subdomains of domains like wwwcrazy.com, jobsearchus.com, likethathouse.com, thewwwinternet.com, freedns.us, etc) you can get free dynamic or static DNS services for your website. For example, if you get a subdomain like yourname.jobsearchus.com (or whatever), you can set up the DNS for that hostname to point to your dynamic or static IP address.
