Magazine Notes

If you don't have a fixed IP address but you want to provide access to your machine by name, what do you do? Use a dynamic DNS (DDNS) service. "The major DDNS providers include DynDNS.org (www.dyndns.org), Tzolkin Corporation (www.tzo.com), and No-IP.com (www.no-ip.com). Pricing for DDNS services for custom domains (your own domain name) is the same at all three providers, at $24.95 per year. But DynDNS.org offers free service if you're willing to use a subdomain on one of their domains (such as "craigswebcam .dyndns.org"). Similarly, No-IP.com offers free service on one of their subdomains, supported by banner ads, or you can pay a one-time charge of $12.95 for a subdomain on one of their domains."
