Yes and no. Glue records make it possible to find the the NS in the first place; you're avoiding a broken chain rather than any risk of loops. zone for example.com mydomain IN NS ns.mydomain.example.com. zone for mydomain.example.com IN NS ns.mydomain.example.com. ns IN A 123.123.123.123 If you have the above, you've properly delegated the mydomain.example.com zone to ns.mydomain.example.com, but you'll never reach anything in that zone, as the only A record for the server is in the zone you're trying to find the server for, and you have no idea where that server is... So you have to put a ns.mydomain.example.com. IN A 123.123.123.123 record in the example.com zone so that recursive lookups can find that one critical address and access the mydomain zone. That's the glue record. -- --Jon Radel jon@radel.com [-- Attachment #2 --] 0 *H 01 0 + 0 *H 100\ ^ Xq0 *H 0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA0 090225041326Z 100225041326Z0^10 URadel10U* Jon Thomas10UJon Thomas Radel1 0 *H jon@radel.com0"0 *H 0 O箩js;:|+\&W4f McjDX&̡ 4g;}we62xrqF?6K#zjdf~pC.l5ծ>f%!T`O\BIe Gv $l\9BbkOBHnKl-q; MlL (ٕ ,OJ%g Cqb!?hض2 y *0(0U 0 jon@radel.com0 U 0 0 *H SWW ƳN&⼮i#E[%Ҟ';uT}|m}^yըO-ʧ}BY p#tc Su Bj8+G$bC4g/qi 77Stڄկ<`SNfT00\ ^ Xq0 *H 0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA0 090225041326Z 100225041326Z0^10 URadel10U* Jon Thomas10UJon Thomas Radel1 0 *H jon@radel.com0"0 *H 0 O箩js;:|+\&W4f McjDX&̡ 4g;}we62xrqF?6K#zjdf~pC.l5ծ>f%!T`O\BIe Gv $l\9BbkOBHnKl-q; MlL (ٕ ,OJ%g Cqb!?hض2 y *0(0U 0 jon@radel.com0 U 0 0 *H SWW ƳN&⼮i#E[%Ҟ';uT}|m}^yըO-ʧ}BY p#tc Su Bj8+G$bC4g/qi 77Stڄկ<`SNfT0?0 0 *H 01 0 UZA10U Western Cape10U Cape Town10U Thawte Consulting1(0&U Certification Services Division1$0"UThawte Personal Freemail CA1+0) *H personal-freemail@thawte.com0 030717000000Z 130716235959Z0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA00 *H 0 Ħ<UsUNʙZ hup [v :aQP 0cZ,p+Z?qV˯< 6$*+w=+>@dקe*TH<a@ dr` 00U 0 0CU <0:08642http://crl.thawte.com/ThawtePersonalFreemailCA.crl0 U 0)U "0 0 10UPrivateLabel2-1380 *H HP . fgCL!6 -6/ P p<ab:~ t%Pb'qW%ݩ9 Oe_N4[5MwV!x!5$ F]_eO1d0`0v0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA ^ Xq0 + 0 *H 1 *H 0 *H 1 090715133832Z0# *H 1` c 7&3٘"0R *H 1E0C0 *H 0*H 0 *H @0+0 *H (0 +71x0v0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA ^ Xq0 *H 1xv0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA ^ Xq0 *H hnD<Y5W%>BqQJoVEQB(z HxYH<5L] tuS5^}PrCDrkwa#rQ"G~6x2bZ< a?;/GF`C<f&K$E2h=|{CO~ MCW uq4ra.urJS&L^S5G81-`h;nGlI2c6ȔIg
