Subject: Poorly configured records for resalehost.networksolutions.com
Hello,
I understand from a bit of searching that Network Solutions replaces or wildcards expired domains with records for resalehost.networksolutions.com, however, this practice is completely misconfigured, and has been so for at least 2 years from old mailing list posts I have found. There are many reports of serious load problems that this practice causes on caching nameservers around the world, and my company has recently seen a large number of occurrences of this issue.
It would be greatly appreciated if someone with some detailed knowledge of DNS RFCs fixes this problem once and for all, for I, personally, am growing weary of being paged in the middle of the night, to find massive amounts of queries for resalehost.networksolutions.com…
It would be quite simple for Network Solutions to reconfigure the wildcard to something proper, or perhaps to do the same as almost every other domain registrar, and simply let old domain records expire, which would result in resolution failure, instead of replacing or wildcarding the expired records improperly, against RFCs, creating a far worse problems for the internet in general.
Please, feel free to contact me on this matter, if you wish.
Kind Regards,
Michael
