record that points to the address. Then, under Network, click DNS, then

only nameservers E2E DNS offers; nameserver names under your own domain are not available. See
Point your domain to E2E nameservers.
I pointed my domain to E2E’s nameservers. Why are there no records?
Section titled “I pointed my domain to E2E’s nameservers. Why are there no records?”The domain also needs to be added in MyAccount. On Manage DNS, click Add Domain, then add its records. E2E’s nameservers answer for the domain as soon as you add it. See Add a domain. If the domain is added and still does not answer, see My domain does not resolve after I pointed it to E2E.
Can I use E2E DNS for a domain I bought somewhere else?

How long does a DNS change take?
Section titled “How long does a DNS change take?”E2E’s nameservers answer with a new record at once, and with an edit or a delete within about
10 seconds. Other DNS servers that looked the name up before keep the old answer until its TTL runs
out. A nameserver change at your registrar can take up to 48 hours to reach every resolver. To see
what E2E answers right now, run dig @ns50.e2enetworks.net.in www.example.com A +short. See
Troubleshooting DNS.
What TTL should I use?
Section titled “What TTL should I use?”3600 seconds, which is one hour, or more, for records that rarely change. Diagnostics flags any record under 3600 seconds. Use a shorter TTL, such as 300 seconds, for a few hours before you move a record. See Add a DNS record.
