Why I am getting a strange DNS server in my dhcp client android phone? Sorry for bad english.
I have a DHCP server router with IP 192.168.0.254
Everything goes well, but my phone and my tablet gets a very strange DNS 1 server: 80980492081

Here is a screenshot:



This is very strange and is getting me mad. I don't know where that strange DNS 1 server comes from. My DHCP server settings are right.

My phone is a Samsung Galaxy S5

Does anybody know what is happening?

Thank you.
An IPv4 address is a 32bit number. The common way to print an IPv4 address is to split it into 4 8bit blocks and separate them with a dot.

However an IPv4 address is also valid in it's decimal/integer representation. This decimal representation is used for your DNS IP address: 80980492081.

Converting the number in the common IPv4 address format ends up with the IP address: 218.208.63.49.
