BEST DDNS service ever!! i really like this service,they are very generous allowing free accounts not to expire and give unlimited dns queries,they have alot of free subdomains for people to choose from and a few extra ones for paid members,the membership fee yearly is only 10.00 which is well worth the service! i highly recommend this service to people!

Super speedy response to a problem. I reported a problem on Saturday 20th May 13:15 - I could not get ddclient (attempting to update a subdomain's IP address) to authenticate after several days trying. I constantly received "bad auth". I received a reply on SUNDAY 21st May in the afternoon explaining that I could not authenticate against a subdomain - I had to use &alias= after the main domain name. I.e. the solution was not complex - the problem being caused by my misunderstanding that some people call subdomains "Alias" of the main domain for some reason. I used to think that CNAME records were aliases to the canonical name and A records were subdomains. Ho hum. However, I think that this is an all-time record for a speedy response to a problem - on a weekend as well! PS I am a paying client of dynu just for the record.

Good services and support. -

Great Dynamic DNS service with a lot of… Great Dynamic DNS service with a lot of options and customizability. I'm using it for at least 2 years now and it works like a charm with no lags or disconnections.

Used to be great... no longer... although my past experience was great, recently the email was having slow-down issues and one day the whole system became unavailable for over 8 hours! They said it was due to an upgrade! Upgrades are scheduled, and after reading their reply (below), it sounds more like they had a BIG failure and no backup plan... I have now switched my email to another provider... Note: I also tried their new VPS service which failed less that 24 hours after being activated (with another lame excuse) If you need reliability, find another provider. Their support reply: We are making significant infrastructure upgrades to ensure the future stability of the service. We expect this to take from 2 to 8 hours. Your emails are being received by the backup node so please rest assured that there is no loss of email.
