Thanks everyone who responded It appears I should have been looking for clue in my own network. Amazon hosts crocker.com and they have the glue records. Apparently left over from when the domain was with Network Solutions. I have tickets open with Amazon to get them removed/updated. -Matt From: NANOG <nanog-bounces+matthew=corp.crocker.com@nanog.org> on behalf of Matthew Crocker <matthew@corp.crocker.com> Date: Tuesday, December 15, 2020 at 11:43 AM To: "nanog@nanog.org" <nanog@nanog.org> Subject: [EXTERNAL]Need someone with clue @ Network Solutions. CAUTION: This email originated from outside of Crocker. Do not click links or open attachments unless you recognize the sender and know the content is safe. I need to get Network Solutions to remove glue records for hosts in my domain. My domain isn’t registered with Network Solutions and they refuse to speak with me as I’m not a customer. I’ve had my customer attempt to update their domain through Network Solutions but the only thing they can change is the NS record, not the underlying host glue record. I don’t think the glue records even need to exist as they are published by my domain already. Does anyone have any contacts at Network Solutions that can help?
