Custom DNS Top Level Domains (TLDs)
The Custom DNS service can be used with almost every top level domain (TLD) name.
As of November 17, 2004, the following TLDs are successfully working with our system:
- Global top level domains (gTLDs) - .com, .net, .org, .edu, .gov
- Sponsored top level domains (sTLDs) - .biz, .info, .aero, .coop, .name, and .pro
- Country code top level domains (ccTLDs) - .ac, .ae, .ag, .ar, .as, .at, .au, .aw, .bb, .be, .bg, .bm, .bo, .br, .by, .bz, .ca, .cat, .cc, .cd, .ch, .cl, .cn, .co, .cr, .cx, .cz, .de, .dj, .do, .ec, .ee, .es, .eu, .fi, .fm, .fr, .gg, .gi, .gl, .gr, .gs, .gt, .hk, .hm, .hr, .ht, .hu, .id, .ie, .il, .im, .is, .it, .je, .jp, .kr, .ky, .la, .li, .lk, .lt, .lu, .lv, .md, .mo, .ms, .mt, .mu, .mx, .my, .no, .nr, .nu, .nz, .pa, .pe, .ph, .pk, .pl, .pt, .ro, .ru, .sa, .se, .sg, .sh, .si, .sk, .st, .tc, .th, .tk, .to, .tr, .tv, .tw, .uk, .us, .uy, .uz, .vc, .ve, .vg, .vn, .vu, .ws, and .za
All other domains in the ICANN root servers (including country TLDs and the new TLDs) should work fine. In fact, it is easier to list the domains with which Custom DNS can not be used.
TLDs which do not work with Custom DNS
- The ccTLDs .nl and .dk have policies that make it difficult or impossible for them to delegate domains to us.
- Domains in "alternate roots" such as new.net or ORSC are not supported. Even if we did support domains in these alternate roots, they would not be accessible from significant portions of the Internet, and thus wouldn't be of much use.
Custom DNS with a "sub-domain" or hostname
If you have control of the DNS (or if your current DNS provider is willing to add the necessary DNS records) for your domain (which can be any domain in the ICANN root servers), you can also delegate a subdomain for use with the Custom DNS service. This can be done by adding NS records delegating the subdomain to ns1.mydyndns.org, ns2.mydyndns.org, ns3.mydyndns.org, ns4.mydyndns.org, and ns5.mydyndns.org. For example, if you are using BIND and want to use the subdomain "dynamic.yourdomain.com", you would add the following to your zone file:
dynamic.yourdomain.com. IN NS ns1.mydyndns.org.
dynamic.yourdomain.com. IN NS ns2.mydyndns.org.
dynamic.yourdomain.com. IN NS ns3.mydyndns.org.
dynamic.yourdomain.com. IN NS ns4.mydyndns.org.
dynamic.yourdomain.com. IN NS ns5.mydyndns.org.
