Comment dyn inc service and alternatives (Score 3, Informative) 223
This thread is worth a read regarding dyndns and their practises.
They recently bought everydns and editdns, offered existing users who paid or donated "free" accounts, and then once they bought it, went back on their word. the free accounts included a migration fee for domains, and the accounts were limited, so users would have to pay again to get the same level of service they may have paid for at editdns for example (and due to dyndns strange pricing where you have a limit of 75 subdomains on the standard paid account, you may have to pay them a significant amount of money)
Also worth noting, then editdns users expressed their concerns, dyndns were very quick to close down their old forum and place with a note to email their staff.
Worth noting that Hurrican Electric have a free dns service (http://dns.he.net) - with up to 50 domains allowed and it can operate as a secondary dns also. They also include a dynamic dns facility. There are some other free options left, but how long until dyndns buys them too ?
