#NIGHTOWL DNS FOR FREE#
Regarding "DDNS yourself" - a good domain registrars providing for free IP updating via their API, all your program need to do is to verify periodically public IP and if it changed send new IP to registrar who will update A(AAAA) record. section why it isn't a good idea to have emails server on residential IP, but there are still a workaround way by using intermediate cheap VPS(virtual private server)) If you don't have static IP then you should forget about mail server if you going with DDNS solution, most email servers either would reject emails from you or will tag email with highest spam level since all dynamic IPs are in PBL lists. That said, do pay attention at how the API works of course you can't be sure that the service doesn't have any vulnerabilities, but if (e.g.) the API runs over unencrypted HTTP and transmits the API key in plain sight, then that's not something you want to rely on. (Unless the provider actually attempts to return false data, which would considerably shorten the company's TTL the moment news websites learn about it.) The DNS server only provides you with an address (much like a phone book) and is not involved in any further communication. Won't they be able to monitor all the traffic flowing through the domain name they provide? That alone isn't something special and could be implemented with any DIY method. I would guess that they allow configuring a very low TTL on the dynamic domains (down to a few seconds), which means it'll drop out of any caches very quickly, at the cost of the DDNS provider itself receiving many more requests (higher load on their DNS servers and databases, and an excuse to charge you more). Is that true? Is there something I've missed? However, several paid DDNS providers I've been looking at seem to promote their ability to have the change take effect near instantaneously (or at least, faster than my DIY-method). The rest of the world doesn't keep a permanent record – it merely caches the results of individual lookups, for the duration indicated in each (sub)domain's "TTL" (Time To Live) field. Only your DNS hosting provider's own systems have to be updated. Here's the thing: when you update your domain-name records in the fashion I've described above, I've read that it may take several hours to propagate throughout the system/world (all DNS servers have to be repopulated with your updated address). Yes, although if the company just provides a generic "host everything" service it might not have any DNS management API at all (focusing instead on web and mail) and you might need to move the domain elsewhere. I just need the API key of the hosting company in order to adjust the necessary domain/IP records programmatically
You need to have a script/program which monitors your IP address periodically, and if the address changes, then the script/app needs to update whatever domain name you're using for your home servers You probably won't have much luck with the mail part. I'm trying to establish a personal mail/calendar server at my home (yes, I've heard that it's difficult, it's a lot of trouble, and so forth, but I'd still like to try). Is that true? Is there something I've missed?Īlso, I have another concern: are there any security issues I may be overlooking with having a DDNS provider? Won't they be able to monitor all the traffic flowing through the domain name they provide? Does anyone have an informed opinion with regard to which method (paid vs. However, I've been doing research, and I've found at least a couple of online resources which explain that you can do DDNS yourself: you need to have a script/program which monitors your IP address periodically, and if the address changes, then the script/app needs to update whatever domain name you're using for your home servers (I happen to have a domain parked with a hosting provider for just this eventuality, and as I understand it, I just need the API key of the hosting company in order to adjust the necessary domain/IP records programmatically.someone let me know if I'm wrong on this and there's a simpler way). I have an ISP that doesn't offer static IP addresses, so it looks like some sort of Dynamic Domain Name Service (DDNS) is the solution.
