Tony, Thank you so much for your help! Your suggestion to use Net::DNS really saved the day, because then I could do a brute force binary search to find the broken DNS record which was screwing me up. Once I deleted that record, all was well in the world, and my AXFR transfers happened just fine.
I owe you a beer or two. Where in the UK are you located? My mom was from Hudderfield (Go Terriers!!!!) Looks like you're in Cambridge for your email, I think I've got a contact there I could get to draw you a few pints maybe. Thanks again, Cheers, John Sr. Storage Architect TOSHIBA AMERICA, INC. 290 Donald Lynch Blvd - Suite 201 Marlborough, MA 01752 508-736-5499 (mobile) E-Mail: john.stof...@toshiba.com Website: Service Now Self Service Portal -----Original Message----- From: Tony Finch <fa...@hermes.cam.ac.uk> On Behalf Of Tony Finch Sent: Tuesday, May 11, 2021 5:24 PM To: Stoffel, John (TAI) <john.stof...@toshiba.com> Cc: bind-users@lists.isc.org Subject: Re: ISC Bind as secondary to Windows Server: bad bitmap error on named xfer.

I had to look at the source, which told me it's to do with NXT records which are super obsolete, so I wonder what weird stuff is in the zone that might cause this. (The NXT record was a predecessor of NSEC; NXT was badly designed so it is unable to support all possible DNS RR types, which is why it needed replacing.) $ rg 'bad bitmap' lib/dns/result.c:137: "bad bitmap", /*%< 94 DNS_R_BADBITMAP */ $ rg BADBITMAP lib/dns/include/dns/result.h:132:#define DNS_R_BADBITMAP (ISC_RESULTCLASS_DNS + 94) lib/dns/rdata/generic/nxt_30.c:154: return (DNS_R_BADBITMAP); lib/dns/result.c:137: "bad bitmap", /*%< 94 DNS_R_BADBITMAP */ lib/dns/result.c:278: "DNS_R_BADBITMAP", Tony. -- f.anthony.n.finch <d...@dotat.at> https://urldefense.com/v3/__https://dotat.at/__;!!BiNunAf9XXY-!VH-JqRCMfVb-2Su9Du-D3OA4DlJi6q3lXIg4s9pjD9fwN1atleDmzsKASzloojK1C1WS$ Viking, North Utsire, South Utsire: Southerly or southeasterly 3 to 5 becoming variable 2 to 4, then northerly 5 to 7 later in Viking and northern North Utsire.
